Talk Title: Finding low-complexity models without the shackles of convexity
Series: AI Seminar
Abstract: In many applications, one wishes to estimate a large number of parameters from highly incomplete data samples. Low-dimensional models such as sparsity, low-rank, etc provide a principled approach for addressing the challenges posed by such high-dimensional data. The last decade has witnessed a flurry of activity in understanding when and how it is possible to find low complexity models via convex relaxations. However, the computational cost of such convex schemes can be prohibitive. In fact, in this talk I will argue that over insistence on convex methods has stymied progress in many application domains. I will discuss my ongoing research efforts to unshackle such problems from the confines of convexity opening the door for new applications.
I will discuss three concrete problems characterized by incomplete information about a low-complexity object of interest. The first is the century-old phase retrieval problem where one wishes to recover a signal from magnitude only measurements--phase information is completely missing. The second is a problem in data analysis, where we observe only a few incomplete linear measurements from a data matrix (e.g. a few entries) and wish to reliably infer all of the entries of the matrix. The third problem involves the recovery of a structured image from highly compressed information--most measurements are missing. To retrieve seemingly lost information I will present novel non-convex algorithms for these problems. Surprisingly, despite the lack of convexity these algorithms can provably converge to the global optimum and hence impute the missing information precisely.
Biography: Mahdi Soltanolkotabi completed his Ph.D. in electrical engineering at Stanford University in 2014. He was a postdoctoral researcher in the Algorithms, Machines, and People AMP lab and the EECS and Statistics departments at UC Berkeley during the 2014-2015 academic year. His research focuses on design and mathematical understanding of computationally efficient algorithms for optimization, high dimensional statistics, machine learning, signal processing and computational imaging. Recently, a main focus of his research has been on developing and analyzing algorithms for non-convex optimization with provable guarantees of convergence to the global optimum.

NL Seminar-Harnessing reviews to build richer models of opinions
Fri, Apr 01, 2016 @ 03:00 PM - 04:00 PM
Information Sciences Institute
Conferences, Lectures, & Seminars
Speaker: Julian McAuley , UCSD
Talk Title: Harnessing reviews to build richer models of opinions
Series: Natural Language Seminar
Abstract: Online reviews are often our first port of call when considering products and purchases online. Yet navigating huge volumes of reviews (many of which we might disagree with) is laborious, especially when we are interested in some niche aspect of a product. This suggests a need to build models that are capable of capturing the complex and idiosyncratic semantics of reviews, in order to build richer and more personalized recommender systems. In this talk I'll discuss three such directions: First, how can reviews be harnessed to better understand the dimensions (or facets) of people's opinions? Second, how can reviews be used to answer targeted questions, that may be subjective or require personalized responses? And third, how can reviews themselves be synthesized, so as to predict what a reviewer would say, even for products they haven't seen yet?
Biography: Dr. McAuley has been an Assistant Professer in the Computer Science Department at the University of California, San Diego since 2014. Previously he was a postdoctoral scholar at Stanford University after receiving his PhD from the Australian National University in 2011. His research is concerned with developing predictive models of human behavior using large volumes of online activity data.

Energy Efficient Memory Circuits: From IoT to Exascale Systems and Beyond
Mon, Apr 04, 2016 @ 10:30 AM - 11:30 AM

Conferences, Lectures, & Seminars
Speaker: Dr. Jaydeep Kulkarni, Staff Research Scientist, Circuit Research Scientist, Circuit Research Lab, Intel Corporation
Talk Title: Energy Efficient Memory Circuits: From IoT to Exascale Systems and Beyond
Abstract: With the rapid advances in computing systems spanning from billions of IoTs (Internet of Things) to high performance exascale super computers, energy efficient design is an absolute must. It is projected that by 2020, around 50 billion internet connected devices will be deployed generating hundreds of zettabytes (1021 bytes) of data. It is estimated that embedded memories can occupy up to 70% of the die area in these devices. These trends clearly indicate the paramount importance of developing energy efficient, dense memory circuits and systems across the entire compute continuum. I will present two energy efficient memory solutions one geared for IoT systems while the other targeted at high performance exascale systems. With extremely low energy budget, IoT systems would need ultralow voltage circuits for always-ON sensing and computing. Low voltage Static Random Access Memory (SRAM) operation is challenging due to conflicting read-stability vs write-ability requirements. I will present two Schmitt Trigger based SRAMs having built-in process variation tolerance for extreme low voltage operation. Measurement results from 130nm test-chips confirm successful operation up to 150mV [JSSC'07, TVLSI'12]. At the other end of compute spectrum consisting of high performance exascale systems, fixed voltage/ frequency guardbands are applied to the nominal operating specifications to guarantee reliable operation in the presence of temperature variations, voltage supply droops, and transistor aging induced degradation. Since most of the systems operate at nominal conditions, the necessary guardbands for these infrequent dynamic variations significantly limit the system energy efficiency. I will present adaptive and resilient domino register file design techniques to realize a unified framework for logic + memory operating on same voltage/frequency domain. Measurement results from a 22nm test-chip demonstrate 21% higher throughput with 67% improved energy efficiency [ISSCC'15, JSSC'16]. I will conclude the seminar by highlighting the interesting areas in memory research for the development of next generation of energy efficient computing systems. These aspects include emerging non-volatile technologies such as STT, and RRAM memories, memory scaling using monolithic 3D integration, logic-in-memory organization / architectures for non von Neumann computing models such as neuromorphic computing, and security/privacy issues in next zettabytes of data.

Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Min-Hsiu Hsieh, University of Technology, Sydney
Talk Title: Markovian Evolution of a Quantum Ensemble and its Long-Term Behavior
Abstract: We extend the theory of quantum Markov processes on a single quantum state to a broader theory that covers Markovian evolution of an ensemble of quantum states. This generalizes Lindblad's formulation of quantum dynamical semigroups. Our formalism includes an explicit form of semigroups, their time derivative-” the infinitesimal generator, a carr'e du champ operator, and matrix *phi-entropy. We find a matrix *phi-Sobolev inequality that governs the exponential decay of the these matrix *phi-entropy. Special cases of the matrix *phi-entropy evaluate to the Holevo quantity and the variance of the ensemble, which allows us to relate our formalism to classical coding over quantum channels. In particular, we show that the convergence rates of two special semigroups-the depolarizing and phase-damping channels-can be explicitly computed. They result in fundamentally different equilibrium situations, for which there is no classical analogy.
Biography: Min-Hsiu Hsieh received his PhD degree in electrical engineering from the University of Southern California, Los Angeles, in 2008. From 2008-2010, he was a Researcher at the ERATO-SORST Quantum Computation and Information Project, Japan Science and Technology Agency, Tokyo, Japan.

Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Edward A. Lee, Professor, University of California Berkeley
Talk Title: Resurrecting Laplace's Demon: The Case for Deterministic Models for Cyber-Physical Systems
Abstract: In 1814, Pierre-Simon Laplace published an argument for determinism in the universe, arguing that if someone (a demon) were to know the precise location and momentum of every atom in the universe, then their past and future values for any given time are completely determined and can be calculated from the laws of classical mechanics. This principle, of course, has been roundly invalidated by quantum mechanics, and yet the laws of classical mechanics continue to be extremely useful for prediction. In this talk, I will argue that models plays different (complementary) roles in engineering and science, and that deterministic models have historically proved proved even more valuable in engineering than in science.
Cyber-physical systems, which combine computation with physical dynamics, may seem on the surface to be a particularly poor match for deterministic models. I will argue that the next big advance in engineering methods must include deterministic models for CPS, and I will show that such models are both possible and practical.

Talk Title: Secure Cloud Computing - A Programming Language Approach
Series: CS Colloquium
Abstract: This lecture satisfies requirements for CSCI 591: Computer Science Research Colloquium
The big data era has dramatically transformed our lives; however, security incidents such as data breaches put sensitive data (e.g. photos, identities, genomes) at risk. To protect users' data privacy, there is a growing trend to build secure cloud computing systems, which enables computation over two or more parties' sensitive data, while revealing nothing more than the results to the participating parties. Conceptually, privacy-preserving computing systems leverage cryptographic techniques (e.g. secure multiparty computation) and trusted hardware (e.g. secure processors) to instantiate a "secure" abstract machine consisting of a CPU and encrypted memory, so that an adversary cannot learn information through either the computation within the CPU or the data in the memory. Unfortunately, evidence has shown that, side channels (e.g. memory accesses, timing, and termination) in such a "secure" abstract machine may potentially leak highly sensitive information including cryptographic keys that form the root of trust for the secure systems.
I conduct synergistic research to bridge cryptography and programming language techniques to address
this problem. My research broadly expanded the investigation of a research direction called trace oblivious computation, where I employ programming language techniques to prevent side channel information leakage. In this talk, I will discuss my work on two promising approaches, i.e. secure-processor and secure multiparty computation, toward building a secure cloud computing system. I will focus on both theoretical development to enforce formal security, as well as practical system building to yield the state-of-the-art results.
Biography: Chang Liu is a PhD candidate in the Department of Computer Science at University of Maryland, College Park, where he works in the Maryland Cybersecurity Lab with his advisors Michael Hicks and Elaine Shi. His work broadly expanded the investigation of the research direction of trace oblivious computation, which made significant impact on trusted hardware-based secure computation and cryptography-based secure multiparty computation. He is the recipient of John Vlissides Award (2015) and University of Maryland's Outstanding Early Graduate Student Award (2014). His papers has received a NSA Best Scientific Cybersecurity Paper Award (2013), the Best Paper Award of ASPLOS (2015), and 1st Best Paper Award in Applied Cyber Security Paper at CSAW (1st Place, 2015). His ObliVM system won the HLI Award for Secure Multiparty Computation in the iDash Secure Genomics Analysis Competition (2015).

Smart Data Pricing
Tue, Apr 05, 2016 @ 11:00 AM - 12:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Carlee Joe-Wong, Princeton University
Talk Title: Smart Data Pricing
Abstract: Data traffic has increased sharply over the past decade and is expected to grow further as Internet applications from video streaming to cloud storage become ever more popular. Yet data network capacity is not expanding fast enough to handle this exponential growth, leading service providers to change their mobile data plans in an effort to reduce congestion. Inspired by these ongoing changes and building on work from the 1990s, smart data pricing (SDP) aims to rethink data pricing for tomorrow's networks. In this talk, I will focus on the temporal and content dimensions of SDP and then briefly discuss the problem of fairly allocating network resources to applications with diverse resource needs. Time-dependent pricing (TDP) proposes to lower short-lived peaks in network congestion by incentivizing users to shift their data usage to less congested times. While TDP has been used in industries such as smart grids, TDP for mobile data presents unique challenges, e.g., it is difficult to predict how users will react to the prices on different days. Thus, we developed algorithms that continually infer users' changing responses to the offered prices, without collecting private data usage information. We implemented these algorithms in a prototype system, which we used to conduct the first field trial of TDP for mobile data. We showed that our TDP algorithms led to significantly less temporal fluctuation in demand, benefiting the service provider and lowering users' data prices overall.
Sponsored data, an emerging form of data pricing offered by AT&T, allows content providers to subsidize their users' data traffic; the resulting revenue can be used to expand existing data networks. We consider the impact of sponsored data on different content providers and users, showing that cost-aware users and cost-unaware content providers reap disproportionate benefits. Simulations across representative users and content providers verify that sponsored data may help to bridge the digital divide between different types of users, yet can exacerbate competition between content providers.
Biography: Carlee Joe-Wong is a Ph.D. candidate and Jacobus fellow at Princeton University's Program in Applied and Computational Mathematics. She is interested in mathematical aspects of computer and information networks, including work on smart data pricing and fair resource allocation. Carlee received her A.B. in mathematics in 2011 and her M.A. in applied mathematics in 2013 both from Princeton University. In 2013-“2014, she was the Director of Advanced Research at DataMi, a startup she co-founded from her data pricing research. Carlee received the INFORMS ISS Design Science Award in 2014 and the Best Paper Award at IEEE INFOCOM 2012. She was a National Defense Science and Engineering Graduate Fellow (NDSEG) from 2011 to 2013.

Speaker: Aaron Schulman , Stanford
Talk Title: Why applications are still draining our batteries, and how we can help.
Series: CS Colloquium
Abstract: This lecture satisfies requirements for CSCI 591: Computer Science Research Colloquium
Application developers lack tools to profile and compare the energy consumption of different software designs. This energy-optimization task is challenging because of unpredictable interactions between the application and increasingly complex power management logic. Yet, having accurate power information would allow application developers to both avoid inefficient designs and discover opportunities for new optimizations.
In this talk, I will show that it is possible to accurately measure system-level power and attribute it to application activities. I will present BattOr, a portable, easy-to-use power monitor that provides developers with a profile of the energy consumption of their designs-”without modifications to hardware or software. I will show how Google developers are using BattOr to improve Chrome's energy efficiency. I will also show how fine-grained understanding of cellular power at different signal strengths enables novel energy optimizations. Finally, I will describe my future plans to attribute system-level power to individual hardware components and to investigate opportunities presented by instrumenting every server in a data center with fine-grained power monitoring.
Biography: Aaron Schulman is a Postdoctoral Scholar at Stanford working with Sachin Katti; he earned his Ph.D. in Computer Science from the University of Maryland, where he was advised by Neil Spring. His research interests are in low-power embedded systems, wireless communication, and network measurement. Aaron's research on the BattOr power monitor has been funded by Google, is being commercialized by his startup Mellow Research, and is becoming Google's de facto standard tool for measuring the energy consumption of the Chrome web browser. For his dissertation, Aaron provided the first observations of fundamental factors that limit the reliability of the Internet's critical last-mile infrastructure.

Speaker: Dr. Samet Oymak, Caltech
Talk Title: Sharp tradeoffs for randomized numerical algorithms: Let the theory meet practice
Series: CommNetS
Abstract: Randomized numerical algorithms are fundamental for a variety of problems in signal processing and machine learning. Examples include sparse signal processing and dimensionality reduction for faster machine learning. These algorithms come with various tradeoffs involving the amount of data, computational resources and statistical precision. Characterization of these tradeoffs is crucial for correct hyperparameter selection, time sensitive optimization and eventual performance of the algorithms. In this talk, we describe our recent results on how to accurately predict these tradeoffs in multiple scenarios which helps us further close the gap between theory and practice.
Biography: Samet Oymak is a software engineer at Google. Prior to that, he was a fellow at Simons Institute and a postdoctoral scholar in the AMPLab at UC Berkeley. He received his BS from Bilkent University in 2009 and his MS and PhD from Caltech in 2014, all in electrical engineering.

Speaker: Rajan N. Chokshi , Accutant Solutions
Talk Title: Artificial Lift Applications in Unconventional & Tight Reservoirs
Abstract: The unique challenges of hydrocarbon production from shale reservoirs have required operators to take a fresh approach to asset development. Decisions about well placement, geometry, completion, and production are interrelated and must be addressed as part of life cycle planning. Artificial lift systems must be configured for rapidly changing and dynamic production environments. Migration from one lift technology to another is often required for wells that typically experience steep production decline rates. This presentation discusses the unique challenges of unconventional production and presents current production trends supported by field examples. Recommendations for optimizing production from shale and tight reservoirs are presented.
Biography: Dr. Rajan Chokshi works as Optimizer for Accutant Solutions of Houston -“ A training and consulting services provider for production optimization.
In a career spanning over 30 years, Chokshi has worked on petroleum and software engineering projects globally in the areas of multi-phase flow, artificial lift design, and production optimization in oil and gas industries for national oil company and service providers. He continues to consult and teach courses in these areas for SPE, universities and other organizations. His interests are developing and nurturing young talent globally, technology integration and commercialization.

AI Seminar-Prominent features of rumors in social networks
Fri, Apr 08, 2016 @ 11:00 AM - 11:45 AM
Information Sciences Institute
Conferences, Lectures, & Seminars
Speaker: Meeyoung Cha , KAIST
Talk Title: Prominent features of rumors in social networks
Series: Artificial Intelligence Seminar
Abstract: *This is the First of 2 AI Seminar Talks on FRI. 4/8
Social psychology literature defines a rumor as a story in general circulation without confirmation or certainty to facts. Rumors arise in the context of ambiguity, when the meaning of a situation is not readily apparent or when people feel an acute need for
Security. Rumors hence are a powerful, pervasive, and persistent force affecting people and groups. This talk will introduce efforts on identifying rumors using massive data in social media. I will discuss the distinct patterns we observed from rumor diffusions in terms of the following aspects: temporal, structural, and linguistic.
(Published at IEEE 13th International Conference on Data Mining Conference 2013, Joint work with Sejeong Kwon, Kyomin Jung, Wei Chen, Yajun Wang)

Speaker: Hao Wu, USC/ISI
Talk Title: Learning Distributed Representations from Network Data and Human Navigation
Series: Natural Language Seminar
Abstract: The increasing growth of network data such as linked documents on the Web and social networks, has imposed great challenges on automatic data analysis. We study the problem of learning representations of network data, which is of critical for applications including data classification, ranking and link prediction. We present neural network embedding algorithms to learn distributed representations of network data that capture the deep context of each data point, and human cognition in navigation data. To improve the scalability of our algorithms, we use efficient optimization and sampling methods.

Meaning and Memory Retrieval: Evidence from Semantic Priming and Sentence Memory
Mon, Apr 11, 2016 @ 10:00 AM - 12:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Peter Gordon, University of Northern Carolina, Chapel Hill
Talk Title: Meaning and Memory Retrieval: Evidence from Semantic Priming and Sentence Memory
Abstract: Semantic priming, where the processing of a word is facilitated when it is preceded by a related word, has generally been taken as evidence of spreading activation, the idea that accessing the meaning of the prime word facilitates recognition of the target word by pre-activating its meaning before it is presented. The idea that pre-activation of meaning by a prime word (or other stimulus) increases the accessibility of words (or other psychological constructs) has spread from cognitive psychology to many other areas including cognitive neuroscience, social influence, psychopathology and the effects of aging. This idea is challenged by a series of studies in my lab that analyzed response-time distributions from newly-developed ocular-response tasks that are performed more quickly than tasks with manual or vocal responses and for that reason give a more direct view of lexical processing; the results show that the semantic relation between the prime and target influences processing only after the target has been seen. The findings are inconsistent with spreading-activation models and instead support alternative models in which the process of retrieving lexical information from the target word is facilitated by the consistent contextual information provided by the prime word. Additional studies on how meaning influences sentence reading and recall demonstrate that explanations based on memory retrieval play a necessary role in explanations of human language processing and that they eliminate the need for expectation-based explanations.
Biography: Dr. Peter C. Gordon received his B.S. in Psychology from Georgetown University in 1975 and his Ph.D. in Experimental Psychology from the University of Michigan in 1984. He was Assistant and Associate Professor in the Psychology Department at Harvard University from 1984 through 1993, and subsequently joined the faculty at the University of North Carolina at Chapel Hill where he is Professor of Psychology and Faculty Fellow at the Frank Porter Graham Child Development Center. He is a Fellow of the Association for Psychological Science and a superannuated member of the Psychological Round Table. He has served as a reviewer for multiple NSF programs (Cognition & Perception, Information & Intelligent Systems and Linguistics) and as a member of the Language and Communication panel at NIH. He served a four-year term as Associate Editor at Psychological Science, has been on the editorial boards of major journals (Cognitive Psychology, JEP:LMC) and is a Consulting Editor at Psychological Review. His awards include appointment as John and Ruth Hazel Associate Professor at Harvard University, a W.N. Reynolds Leave from the University of North Carolina and a James McKeen Cattell Fund Sabbatical Award that is supporting his visit to USC this semester.
Dr. Gordon's program of research focuses on uncovering the psychological basis of language comprehension and production, with a particular focus on the nature of discourse coherence and on the interaction of discourse-level processing and lower-level processes such as word recognition. His research on the processing of written and spoken language has been highly interdisciplinary, including long-term collaborations with researchers trained in computer science, linguistics and neuroscience, as well as researchers with clinical specializations. His recent research has involved coordinated use of behavioral and neural methods for studying how language processing is coordinated with perception, attention, memory and motor control, and has additionally involved development of eye-tracking and computational-linguistic methods for studying cognitive and interpersonal processes in normal and impaired populations.

Security and Privacy of Non-Volatile Memories- Vunerabilities, Attack Models and Preventions
Mon, Apr 11, 2016 @ 10:30 AM - 11:30 AM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Swaroop Ghosh, Professor, University of South Florida
Talk Title: Security and Privacy of Non-Volatile Memories- Vulnerabilities, Attack Models and Preventions
Abstract: Non-volatile memories (NVM) such as Spin-Transfer Torque RAM (STTRAM), Resistive RAM and Domain Wall Memory have drawn significant attention due to complete elimination of bitcell leakage. In addition to plethora of benefits such as density, non-volatility, low-power and high-speed, majority of NVMs are also compatible with CMOS technology enabling easy integration. NVMs are particularly interesting for a class of Internet-of-Things (IoT) that are normally OFF but require instant ON experience. Although promising, I will show that NVMs bring new security and privacy challenges that were absent in their conventional volatile memory counterparts. Assuring data integrity and privacy against malicious attacks is particularly critical on deployed systems that are hard to maintain and enforce physical security. I will present two aspects to NVM security in Last Level Cache (LLC) using STTRAM as test case:
(i) Data integrity which pertains to data corruption by malicious attack with the intention to launch denial-of-service. Such attacks exploit the fact that NVMs are fundamentally susceptible to ambient parameters such as magnetic field and temperature. I will describe these vulnerabilities and attack models, and, propose two micro-architectural techniques to assure data integrity under attack namely, cache bypassing and checkpointing. These techniques allow seamless computation in presence of attack at minimal design overhead.
(ii) Data privacy which pertains to sensitive data such as keys and passwords being compromised. Storage such as Hard Disk Drive (HDD) has been the non-volatile part of memory system traditionally protected by encryption. Although effective, the latency associated with encryption makes it non-trivial for application in higher levels of memory stack such as LLC. I will present the vulnerabilities and attack models, and, propose two low-overhead techniques to maintain data privacy namely, Semi Non-Volatile Memory which is similar to NVM but with very low retention time so that the data vanishes after power is turned OFF, and, irreversible erasure of data at power down using residual charge from power rail.

Speaker: Sudhakar Yalamanchili, Professor, Georgia Institute of Technology
Talk Title: New Rules: Sustaining Performance Scaling in a Physical World
Abstract: As industry moves to increasingly small feature sizes, performance scaling will become increasingly dominated by the physics of the computing environment. Sustaining performance scaling will require understanding, characterizing, and collaboratively managing the multi-physics and multi-scale (nanoseconds to milliseconds) transient interactions between the delivery, dissipation, and removal (cooling) of power and their impact on system level performance. There are fundamental trade-offs to be made in processor design at the microarchitectural level between performance, energy/power, reliability, and packaging. In particular, these tradeoffs become increasingly pronounced with heterogeneity and diversity of application workloads. This talk will describe how interacting physical phenomena, e.g., thermal coupling, i) limits performance scaling, ii) drives application-driven microarchitecture-level tradeoffs, and iii) leads to operational principles for energy-efficient heterogeneous many core architectures. In particular, the talk will cover some exemplar implementations on modern integrated CPU-GPU architectures.
Biography: Sudhakar Yalamanchili earned his Ph.D. degree in Electrical and Computer Engineering from the University of Texas at Austin. Upon graduation, he joined Honeywell's Systems and Research Center in Minneapolis working on embedded multiprocessor architectures.

Thomas Lord Department of Computer Science
Conferences, Lectures, & Seminars
Speaker: Kobbi Nissim, Dept. of Computer Science, Ben-Gurion University and Center for Research on Computation and Society, Harvard University
Talk Title: Privacy: From Theory to Practice
Series: CS Colloquium
Abstract: This lecture satisfies requirements for CSCI 591: Computer Science Research Colloquium
The treatment of privacy in data analysis has taken a dramatic shift a little more than a decade ago - as failures of traditional privacy preserving techniques were beginning to accumulate, a theoretical, foundational approach to privacy emerged. A central concept in this theoretical treatment is "differential privacy", a definition of privacy in the context of data analysis that has concrete provable privacy consequences. Differential privacy became to be a rich, fast evolving framework for developing privacy preserving algorithms and for studying some of the fundamental properties of privacy. Moreover, differential privacy proved to interact fruitfully with many other research areas, and even to influence applications that are (seemingly) not related to privacy. With a mature theoretical basis, differential privacy is now at prime time for inclusion in real-world systems.
We will look into the intuition behind differential privacy, review some of is theory, and some of the challenges towards using differential privacy in practice. In particular, we will focus on a new legal-technological methodology for making rigorous claims that differential privacy satisfies existing legal privacy regulations.
The talk would be self-contained and no prior background on privacy would be assumed.

CS Colloquium: Qixing Huang (Toyata Technical Institute Chicago) - Visual Computing Using Big 3D Data
Tue, Apr 12, 2016 @ 04:00 PM - 05:00 PM
Thomas Lord Department of Computer Science
Conferences, Lectures, & Seminars
Speaker: Qixing Huang, Toyata Technical Institute Chicago
Talk Title: Visual Computing Using Big 3D Data
Series: CS Colloquium
Abstract: This lecture satisfies requirements for CSCI 591: Computer Science Research Colloquium
Over the past decade, the quantity of accessible visual data has undergone unprecedented expansion. This data is not only vast but also exists within numerous modalities such as images, videos, and 3D models. While researchers have aptly exploited the inflation of these first two areas, the significant growth in 3D data has been predominantly overlooked. In this talk, I will present algorithms that utilize big 3D data to accomplish many previously hard or even impossible tasks in visual computing. These include reconstructing complete 3D models from single images, identifying meaningful correspondences between drastically different objects (e.g., between an elephant and a cat) as well as extracting semantic parts of an object without supervision. The guiding principle is to establish high-quality maps for aggregating and propagating information. I will discuss fundamental map computation tools for large-scale datasets.
Biography: Qixing 'Peter' Huang is currently a research assistant professor at the Toyata Technical Institute in Chicago. He obtained his PhD in Computer Science from Stanford University and his MS and BS in Computer Science from Tsinghua University. He has also worked at Adobe Research and Google Research, where he developed some of the key technologies for Google Street View. Dr. Huang's research spans the fields of computer vision, computer graphics, and machine learning. In particular, he is interested in designing new algorithms that process and analyze big geometric data (e.g., 3D shapes/scenes). He is also interested in statistical data analysis, compressive sensing, low-rank matrix recovery, and large-scale optimization, which provides theoretical foundation for his research. Qixing has published extensively at SIGGRAPH, CVPR and ICCV, and has received grants from NSF and various industry gifts. He also received the best paper award at the Symposium on Geometry Processing 2013.

Speaker: Peter Kairouz, University of Illinois at Urbana-Champaign
Talk Title: The Fundamental Limits of Data and Metadata Privacy
Abstract: With the ability to surf the web efficiently comes the danger of being monitored. There is an increasing tension between the need to share data and the need to preserve the privacy of Internet users. The need for privacy appears in two main contexts: the data privacy context, as in when individuals want to share their personal data with a potentially malicious service provider or when a trusted service provider wants to release sensitive information about individuals, and the metadata privacy context, as in when individuals want to broadcast information on a social network without the fear of being judged by friends, the public or authorities.
In the metadata privacy context, anonymity is achieved by controlling the way information spreads over a network. In the first half of my talk, I will introduce a novel anonymous messaging protocol (called adaptive diffusion) and show that it spreads a message quickly over a network while "perfectly" hiding authorship information from a powerful adversary with global access to metadata.
In the data privacy context, privacy is achieved by randomizing the data before releasing it. This leads to a fundamental trade-off between privacy and utility. In the second half of my talk, I will present a new class of privacy mechanisms (called staircase mechanisms) and show that they achieve the optimal privacy-utility trade-off under various settings of interest.

Materials Science for III-V/Si Multijunction Solar Cells

Mork Family Department of Chemical Engineering and Materials Science
Conferences, Lectures, & Seminars
Speaker: Professor Steven A. Ringel, The Ohio State University
Talk Title: Materials Science for III-V/Si Multijunction Solar Cells
Series: Lyman Handy Colloquia
Abstract: Creating a cost-effective, implementable photovoltaic (solar cell) technology is a great and challenging problem for electronic materials research. The premium on utilizing the solar spectrum efficiently is met in importance by the need to do so at low cost and in a manufacturing-friendly, large-scale format. For many years, these often conflicting goals have motivated the desire to integrate high efficiency, III-V compound semiconductor photovoltaics, with their proven high solar energy conversion efficiencies (concentrator multijunction efficiencies exceed 45%), with Si and its existing, low-cost manufacturing industry. There has been tremendous progress toward the creation of Si-based multijunction solar cells in recent years, attributable largely to solving defect issues related to the epitaxial integration of III-V semiconductors (GaAs, GaAsP, GaP)
with group IV substrates (Si, SiGe, Ge). By achieving a defect-controlled III-V/IV heterovalent interface, one can subsequently grow high quality III-V solar cells on top of
the substrate and depending on choice of material, one can also make use of the Si growth substrate itself as a sub-cell within a true III-V/Si multijunction design. This
presentation will focus on our efforts to develop Si-based tandem and triple junction solar cells in which the Si substrate serves a dual use -“ as a low cost growth substrate
and as a high efficiency bottom junction for these unique multijunctions. Indeed this Si-based design also captures the ideal set of bandgaps for maximum efficiency and
therefore has the potential to solve the long-standing conundrum of performance and cost goals for photovoltaics.

Speaker: Norman Abramson, Professor Emeritus / University of Hawaii
Talk Title: ALOHA to the Web
Series: Viterbi Lecture
Abstract: Wireless access to the Internet today is provided predominantly by random access ALOHA channels connecting a wide variety of user devices. ALOHA channels were first analyzed, implemented and demonstrated in the ALOHA network at the University of Hawaii in June, 1971. Information Theory has provided a constant guide for the design of more efficient channels and network architectures for ALOHA access to the web.
In this talk we examine the architecture of networks using ALOHA channels and the statistics of traffic within these channels. That traffic is composed of user and app oriented information augmented by protocol information inserted for the benefit of network operation. A simple application of basic Information Theory can provide a surprising guide to the amount of protocol information required for typical web applications.
We contrast this theoretical guide of the amount of protocol information required with measurements of protocol generated information taken on real network traffic. Wireless access to the web is not as efficient as you might guess.
Biography: Norman Abramson received an A.B. in physics from Harvard College in 1953, an M.A. in physics from UCLA in 1955, and a Ph.D. in Electrical Engineering from Stanford in 1958.
He was an assistant professor and associate professor of electrical engineering at Stanford from 1958 to 1965. From 1967 to 1995 he was Professor of Electrical Engineering, Professor of Information and Computer Science, Chairman of the Department of Information and Computer Science, and Director of the ALOHA System at the University of Hawaii in Honolulu. He is now Professor Emeritus of Electrical Engineering at the University of Hawaii. He has held visiting appointments at Berkeley (1965), Harvard (1966) and MIT (1980).
Abramson is the recipient of several major awards for his work on random access channels and the ALOHA Network, the first wireless data network. The ALOHA Network went into operation in Hawaii in June, 1971. Among these awards are the Eduard Rhein Foundation Technology Award (Munich, 2000), the IEEE Alexander Graham Bell Medal (Philadelphia, 2007) and the NEC C&C Foundation Award (Tokyo, 2011).

Information Sciences Institute
Conferences, Lectures, & Seminars
Speaker: Morteza Dehghani (USC), USC/ISI
Talk Title: Decoding Neuro-Semantic Representation of Stories across Languages
Series: Natural Language Seminar
Abstract: Understanding how conceptual knowledge is represented and organized in the human brain is one of the core problems of cognitive science, and many studies have aimed at exploring and understanding the similarities of neuro-semantic representations of concepts. A general approach that has been particularly fruitful in this domain is the investigation of the relationship between various corpus statistics of words and neural activity during exposure to those words. In this work, we examine the neuro-semantic representations of stories across three different languages. We demonstrate that using new advances in vector-based representation of text and paragraphs, fMRI signals can be reliably mapped to story representations. We also show that such representations can capture common neuro-semantic representation of stories across different languages. Finally, performing search-light analysis using over a billion regressions, we show that activation patterns in the default mode network of the brain are the most reliable features for decoding stories.
Biography: Morteza is an Assistant Professor of psychology, computer science and the Brain and Creativity Institute at University of Southern California. His research spans the boundary between psychology and artificial intelligence, as does his education. His work investigates properties of cognition by using documents of the social discourse, such as narratives, social media, transcriptions of speeches and news articles, in conjunction to behavioral studies.

Speaker: Peter Fennell, Postdoc at Univ. of Limerick, Ireland
Talk Title: Information diffusion on Twitter: a hazard rates approach
Series: AI Seminar
Abstract: Online social networks provide a digital footprint of the manner in which people interact in their everyday lives. Information diffuses through online social networks as a result of users creating and sharing information, and such diffusions are highly complex because of the nature of individuals and because of the structure of the network that connects them.
In this talk, I will discuss an approach to understanding information diffusion on online social networks, with specific reference to a case study on Twitter. Here, we use hazard rates to quantify how individuals respond to information, and show the non-linear nature of the response of individuals to multiple signals from their peers. Such hazard rates can be implemented in mathematical frameworks for understanding and predictive purposes, allowing us to analyze the information diffusion and its dependence on the structure of the online social network. I will discuss the importance of empirical observations of large social network datasets in constructing mathematical models of information diffusion, and the necessity of such realistic models for both prediction and analysis.
Biography: Peter Fennell is a postdoctoral researcher in the Dept. of Mathematics and Statistics in the University of Limerick, Ireland. Peter's research focuses on diffusive processes on complex networks, and in using probabilistic frameworks to understand such processes and their interplay with the network through which they spread. Recently, Peter has been awarded a James S. McDonnell postdoctoral fellowship to further his research in the area of information diffusion on online social networks. This project will combine extensive empirical examinations of online social networks along with mathematical modeling to gain an understanding of the underlying mechanisms behind information diffusion

Talk Title: Multimodal neuroimaging to detect early neural dysfunction and measure neural enhancement in Alzheimer's disease
Abstract: Alzheimer's disease is the most common cause of cognitive impairment in older adults. Over 5 million people in the US are affected and this number is expected to triple by 2050. In concert with clinical trials, identifying effective ways to detect early neural changes and to measure longitudinal change in the preclinical stages of Alzheimer's disease is critically needed. In this presentation, I will discuss my research aimed at using multimodal neuroimaging methods to detect early changes in vulnerable brain regions important for executive function and memory and how these neural alterations affect large-scale brain networks. Ongoing studies focus on the role of regional Alzheimer's pathology using PET and network integrity using MRI and how these changes may be remediated through clinical interventions, like exercise in older adults at risk for Alzheimer's disease. Lastly, I will discuss upcoming plans to integrate new technology, equipment, and ideas to further enhance this research at USC.
Biography: Judy Pa is an assistant professor at the Institute for Neuroimaging and Informatics in the Keck School of Medicine and the department of Neurology. Judy's research is focused on identifying individuals at risk for Alzheimer's disease using multimodal neuroimaging techniques, understanding how Alzheimer's pathology impacts brain function in the living brain, and developing ways to remediate cognitive and brain dysfunction using modifiable lifestyle factors, like exercise. Her research program is supported by the National Institute on Aging, Alzheimer's Association, and Springer Medical Fund.
Judy is dedicated to teaching and enjoys training and mentoring students in USC's Neuroscience Graduate Program, Keck School of Medicine, and new Neuroimaging and Informatics Masters of Science program.

Talk Title: The Secret Life of Mobile Applications
Series: CS Colloquium
Abstract: This lecture satisfies requirements for CSCI 591: Computer Science Research Colloquium
As software becomes increasingly more complex and yet more pervasive, poor understanding of software behavior compromises the quality and the integrity of software systems that we use. In this talk, I will show that automated analysis techniques can help to identify and reason about software behavior characteristics that matter to humans. After a brief overview of my current research directions, I will focus on techniques for identifying privacy violations in mobile applications, i.e., leakages of sensitive information such as user location and shopping preferences. I will present a set of solutions that rely on contextual, functional and usage-based clues for improving the accuracy of leakage detection and for distinguishing between "legitimate" and "illegitimate" information distribution patterns.
Biography: Julia Rubin is a Postdoctoral Researcher in the EECS department at MIT. Prior to that, she was a Research Staff Member and, part of the time, a manager at IBM Research in Haifa, Israel. She received her PhD in Computer Science from the University of Toronto, Canada in 2014. Julia's research interests are in software engineering, program analysis and software security, focusing on improving the quality and the integrity of modern software systems. Her recent work in this area won an ACM Distinguished Paper Award at ASE, two Best Paper Awards, at SPLC and CSMR, and was nominated for Facebook's Internet Defense Prize at the USENIX Security Symposium.

Speaker: Walid Saad, Assistant Professor, Virginia Tech
Talk Title: Behavioral Game Theory in Cyber-Physical Systems: Frameworks and Applications
Abstract: Cyber-physical systems (CPSs) are characterized by three key features: heterogeneity, in terms of technology, services, and human interactions, dynamics, in terms of rapidly varying environments and uncertainty at both the cyber and physical realms, and size, in terms of number of users, devices, and services. These characteristics motivate the need for distributed optimization and control solutions that can lay the foundations of smart and secure CPSs. In this respect, game theory is expected to play a critical role towards deploying such intelligent CPSs in which cyber-physical devices, and possibly humans, can make independent and strategic decisions, smartly adapting to their environment. In particular, the presence of humans in the CPS loop motivates the adoption of game-theoretic methods that go beyond classical game theory in which agents are assumed to be objective, fully rational, and uninfluenced by real-world perceptions. Capturing such practical CPS considerations within game-theoretic constructs can be achieved via suitable notions of bounded rationality and behavioral considerations. In this talk, we will investigate the role of behavioral game theory in CPS design while delineating emerging frameworks in that field with a focus on two key CPS domains: (i)- Consumer-centric energy management in the smart grid and (ii)- Cyber-physical systems security. We conclude the talk by discussing other ongoing research activities in our group.

Talk Title: Hematopoietic stem cell function in stress, disease and aging
Series: Eli and Edythe Broad Center for Regenerative Medicine and Stem Cell Research at USC Distinguished Speakers Series
Abstract: Our research focuses on understanding the general defense mechanisms used by hematopoietic stem cells (HSC) to protect blood production during the lifetime of an ever-changing organism. This fundamental question is central to tissue maintenance and regeneration, and has implications for every aspect of adult physiology ranging from response to stress, development of diseases and biology of aging. Our laboratory is interested in identifying the mechanisms controlling HSC activity in normal and stress conditions, and in understanding how they are affected during disease development and in physiological aging. Our goal is to identify affected genes and pathways that could be used to develop new therapies to treat human diseases and help combat aging.

Speaker: Dr. Vijay Gupta, University of Notre Dame
Talk Title: Cyber-Physical-Human Systems: Results and Challenges
Series: CommNetS
Abstract: Advances in networking and information technology have permitted us to integrate cyber and physical components to design complex systems in fields as diverse as critical infrastructure control, automotive systems, energy conservation, environmental monitoring, and robotics. As we aim to endow such systems with higher levels of autonomy, we have to consider explicitly their interaction with people at multiple layers and in various roles. It is increasingly clear that one of the next frontiers for autonomous systems is to be able to design such cyber-physical-human systems in a systematic and scalable manner. This will naturally require integration of models, tools, constraints and techniques from the individual disciplines. I will cover some examples from our recent work that illustrate this theme. I will begin with the problem of phantom demand response in smart grid which arises when strategic customers seek to maximize their gain by anticipating the control signals that will be used. Then, I will present our recent work on cyber-physical system security that considers malicious intruders seeking to attack the physical system through hijacking the cyber components. Finally, I will show how extending some classical control tools such as passivity and dissipativity to consider cyber components explicitly can help guarantee properties such as composability that are desirable in complex systems. I will finish with some thoughts on challenges that face us in the design of cyber-physical-human systems.
Biography: Vijay Gupta is the College of Engineering Collegiate Associate Professor of Electrical Engineering at the University of Notre Dame, having joined the faculty in January 2008. He received his B. Tech degree at Indian Institute of Technology, Delhi, and his M.S. and Ph.D. at California Institute of Technology, all in Electrical Engineering.

Ultrafast & Broadband Photonic Signal Processing
Thu, Apr 21, 2016 @ 02:00 PM - 03:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Andrew M. Weiner, Purdue University
Talk Title: Ultrafast & Broadband Photonic Signal Processing
Abstract: Lasers capable of generating picosecond and femtosecond pulses of light are now firmly established and widely deployed. Going beyond simple pulse generation, the programmable shaping of ultrafast laser fields into arbitrary waveforms has resulted in substantial impact, both enabling new ultrafast science and contributing to applications in high-speed signal transmission. The lecture begins with an introduction to methods permitting shaping of ultrafast laser fields on time scales too fast for direct electronic control. Recent research areas in the Purdue University Ultrafast Optics and Fiber Communications Laboratory drawing on ultrafast pulse shaping are then reviewed. I first discuss photonically-assisted radio-frequency arbitrary waveform generation with application to spatial and temporal focusing of ultrabroadband wireless signals distorted by antennas or multiply scattering indoor propagation environments. In a second example, I describe recent experiments in which pulse shaping is applied in the regime of quantum optics to manipulate the wave packets of correlated photon pairs. A final example pertains to broadband optical frequency comb fields generated via nonlinear wave mixing in chip-scale microresonators pumped by a single-frequency laser. Line-by-line shaping of such fields permits compression into high repetition rate femtosecond pulse trains and furnishes insight into their coherence.
Biography: Andrew Weiner is the Scifres Family Distinguished Professor of Electrical and Computer Engineering at Purdue University. In 2008 he was elected to membership in the National Academy of Engineering and in 2009 was named a Department of Defense National Security Science and Engineering Faculty Fellow.

Moderating Factors in Predicting Substance Use: Listening to Therapists and Clients Interact
Mon, Apr 25, 2016 @ 10:00 AM - 11:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Paul C. Amrhein, Columbia University
Talk Title: Moderating Factors in Predicting Substance Use: Listening to Therapists and Clients Interact
Abstract: During psychotherapy, and motivational interviewing (MI), in particular, the counselor and client construct a conversation. Besides treatment-specific mechanisms invoked by the counselor (e.g., exploration of ambivalence), the content of this conversation is the result of well-learned discourse mechanisms entailing language fluency, communication skills, goal-directed motivation and social learning, shared by orparticular to these individuals. Shared discourse mechanisms can enable but disparate mechanisms can inhibit a conversation that reliably leads to improved treatment outcomes. Important in this regard is the extent of mutual speaker entrainment at phonetic, morphological, syntactic, and pragmatic levels. The pragmatic level, specifically, speech acts, will be the focus of my talk, as I discuss how matches and mismatches in counselor and client discourse mechanisms can promote or derail the therapeutic conversation, triggering,e.g., client face management, that can skew the meaning and prognostic value of client talk, as a measure of therapeutic engagement and treatment outcomes. The Technical Hypothesis of MI posits that counselor verbal behavior indirectly influences unhealthy client behavior through increases in the strength or frequency of client change talk. Poorly understood, however, is whether or how counselor and client language indices (measured by MITI, MISC or DARNC coding schemes), as markers for discourse mechanisms, interact to determine the predictive value of client change talk.I will present findings of two recent MI training studies based on Swedish Corrections exit interviews and New York City community treatment sessions for substance abuse to demonstrate how and why change talk does not always lead to behavior change.To better understand how the MI conversation engages mechanisms of change, it is clearly important to understand when it doesnt.
Biography: Dr. Amrhein has attracted national and international attention for his research on motivational interviewing and the study of commitment language. He earned his PhD in Experimental Psychology and M.A. in Linguistics from the University of Wisconsin-Madison. His research has important implications for understanding and predicting changes in drug use. He is an Adjunct Associate Professor of Medical Psychology at Columbia University in New York and he holds a tenured faculty position in the Department of Psychology at Montclair State University in New Jersey. Dr. Amrhein also served on the faculty of the University of New Mexico, where he worked closely with Dr. William R. Miller on studies of motivational interviewing.

Alfred E. Mann Department of Biomedical Engineering
Conferences, Lectures, & Seminars
Speaker: Bruce Wheeler, PhD, Emeritus Professor (University of Florida), Dept. of Biomedical Engineering
Talk Title: Perspectives on BME: from Editorial Review of Papers to the Role of Informatics Technologies on the Future
Abstract:
TIPS FOR SCIENTIFIC WRITING AND WHAT EDITORS AND REVIEWERS ARE LOOKING FOR
This is a seminar aimed for students of all ages who wish to improve their writing skills for the purpose of publishing scientific papers. The presentation is a combination of two presentations available at the IEEE EMBS GOLD (Graduates Of the Last Decade) site: http://www.gold.embs.org/resources.html, originally given by Michael Neuman and Bruce Wheeler. Dr. Wheeler relates a number of issues that are important to reviewers and editors which, if carefully considered, can greatly increase the odds of acceptance. He also gives a shortened version of the materials presented by Dr. Neuman on the classic structure of a scientific article.
Perspectives on Health Informatics
This talk gives and overview of the predominance, both current and future, of the field of biomedical and health informatics in shaping the future of health care delivery. Implicit is the argument that the future is exceptionally bright for biomedical engineers, especially those cross-trained in physiology and molecular biology on the one hand and computational science and engineering on the other. There will be growing application in genomic and molecular bioinformatics, as well as multiscale computational modeling of physiological systems. Still the greatest growth and employment will be in the medical and health informatics that are integral to the delivery of healthcare world wide, in both advanced and advancing nations. IEEE EMBS, like other computationally strong biomedical engineering societies, sees great growth for our members and students and is developing programs to help serve their needs.
Biography: Dr. Wheeler's research interests lie in the application of electrical engineering methodologies to neuroscience. His work influenced the development of neural spike sorting technologies, demonstrated that microelectrode array recording from brain slices was possible and productive, and has been a leader in the development of lithography to control cells, especially neurons, in culture. This work aims at basic science understanding of the behavior of small populations of neurons, in hopes of creating better insight into the functioning of the brain.

Speaker: Joao Hespanha, UC Santa Barbara
Talk Title: Opportunities and Challenges in Control Systems arising from Ubiquitous Computation and Communication
Abstract: Advances in VLSI (Very Large Scale Integration) design and fabrication have resulted in the availability of low-cost, low-power, small-sized devices that have significant computational power and are able to communicate wirelessly. In addition, advances in MEMS (Micro Electric Mechanical Systems) technology have resulted in wide availability of solid-state sensors and actuators. The net result is ubiquitous sensing, communication, and computation that can be incorporated into small low-power devices.
In this talk, I will discuss how the above-mentioned technological advances present important opportunities and interesting challenges for control system designers. To this effect, I will discuss how the introduction of digital communication in control loops gives rise to a need for new tools for the design and analysis of feedback control systems. I will also describe recent work demonstrating that feedback control based on on-line optimization is a viable approach to solve a wide range of control problem.

Talk Title: Reprogramming and its application in Rhett Syndrome
Series: Eli and Edythe Broad Center for Regenerative Medicine and Stem Cell Research at USC Distinguished Speakers Series
Abstract: Overexpression of four factors (Oct4, Sox2, Klf4, Myc, or Oct4, Sox2, Nanog, Lin28) reprograms somatic cells to become induced pluripotent stem cells (iPSCs). Reprogramming accompanies genetic and epigenetic changes. We will investigate the molecular mechanism of somatic cell reprogramming. iPSCs provide an incredible resource for cell-based therapy, in vitro disease model and screening drugs. We apply the iPSCs to investigate one of the most prevalent female mental retardation disorders called Rett syndrome.

Information Sciences Institute
Conferences, Lectures, & Seminars
Speaker: Zhengping Che, USC
Talk Title: Deep learning solutions to computational phenotyping in health care
Series: Natural Language Seminar
Abstract: Exponential growth in electronic health care data has resulted in new opportunities and urgent needs to discover meaningful data-driven representations and patterns of diseases. Recent rise of this research field with more available data and new applications also has introduced several challenges. In this talk, we will present our deep learning solutions to address some of the challenges. First, health care data is inherently heterogeneous, with a variety of missing values and from multiple data sources. We propose variations of Gated Recurrent Unit (GRU) to explore and utilize the informative missingness in health care data, and hierarchical multimodal deep models to utilize the relations between different data sources. Second, model interpretability is not only important but necessary for care providers and clinical experts. We introduce a simple yet effective knowledge distillation approach called interpretable mimic learning to learn interpretable gradient boosting tree models while mimicking the performance of deep learning models.
Biography: Zhengping Che is a third year PhD candidate in the Computer Science Department at the University of Southern California, advised by Professor Yan Liu. Before that, he received his bachelor degree in Computer Science from Pilot CS Class (Yao Class) at Tsinghua University, China. His primary research interest lies in the area of deep learning and its applications in health care domain, especially on multivariate time series data.
