Talk Title: Adaptive Clinical Trial Design to Address Acquired Resistance and Therapeutic Failure
Abstract: One of the challenges facing immunotherapy as a durable therapeutic approach in a variety of metastatic cancers is the development of acquired resistance and subsequent therapeutic failure. Widespread clinical applicability of immunotherapy to solid tumors depends on the understanding of response and resistance mechanisms that are mediated by evolving interactions between the immune system and cancer cells. These dynamic interactions are increasingly being identified through longitudinal molecular analysis and immunological profiling and combine to produce an evolving measure of a patient cancer-immune status. However, cancer immune dynamics have yet to be formally quantified and studied as an evolutionary process in the context of immunotherapy clinical trials. To address this, we propose a method to integrate high dimensional, heterogeneous, longitudinal patient-derived cancer and immunological clinical data sets to identify cancer immune dynamics as well as a control theoretic method to preemptively address the onset of resistance through the prediction and synthesis of actionable immunotherapy combination strategies. We apply these methods to genomic and immunological data collected from a patient with recurrent multifocal glioblastoma that elicited a complete response and eventually recurred while enrolled in City of Hope's ongoing IL13R 2-targeting chimeric antigen (CAR) T cell trial for patients with recurrent glioblastoma. We show that dynamic treatment strategies are necessary for the control of tumors with high antigen heterogeneity and propose this as a framework by which to assess the effectiveness of adaptive clinical trial design and patient stratification for combination immunotherapy trials.

Talk Title: Statistical modeling and process data analytics for smart manufacturing
Abstract: Smart manufacturing has been the focus of many researchers and has been extended to varies areas. With the increased complexity of the manufacturing process and the variety data collected from various aspects throughout the process, process data analytics is thus essential to discover process knowledge and predict the future production. In this dissertation, we introduced two challenges accompanied by smart manufacturing and discussed how we handle the challenges for processes with different manufacturing characters. The two challenges are "complexity" and "variety", the areas of applications are additive manufacturing (AM) and pharmaceutical manufacturing.
To handle the challenges accompanying with AM, we first study a statistical modeling and optimal compensation approach to predict and improve the shape accuracy of AM printed parts, especially for the out-of-plane deviation. This method is data driven and thus, not blocked by the complicated AM physical mechanism. Moreover, this method is able to deal with low volume sample data and high volume geometric variety. The feasibility and effectiveness of this approach is proved by experimental study.
To deal with the challenges accompanying with pharmaceutical manufacturing, we proposed a two-stage strategy to study a large-scale cell culture manufacturing process variability. This strategy not only adopts multivariate analysis (MVA) and machine learning (ML) methods on intricate multiple-step bio-processes, but also takes use of multilevel heterogeneous datasets to unveil hidden process characteristics and provide insights into factors affecting process quality. This strategy has been applied to a real antibody pharmaceutical manufacturing, pointing to new cues for domain experts to better understand the process.

Talk Title: Metabolic Complexity. Is there Music Behind it?
Abstract: The complexity of metabolic networks would appear to fit in more appropriately with a cacophonic scenario than anything remotely musical. However, this talk will attempt to show that a mathematical view can be had of this complex process in which the phenomenon of metabolic regulation can be likened to the conductor of a symphonic orchestra summoning combinations of instruments representing metabolic reactions towards superlative music. It will be the objective of this seminar to let this analogy lead the discussion of a cybernetic theory of cellular metabolism which interprets the diversity of gene expression as a targeted effort to maximize the organism's survival. The applicability of the model to bioprocess engineering is demonstrated.

Talk Title: How Can We Advance Structural Quality Analysis with Standards and Machine Learning?
Series: Systems and Software Qualities Tradespace Analysis
Abstract: The C-suite is fed up with software disasters putting the quarterly statement at risk as they digitize the business. They will demand more accountability and force improvements in software processes that may clash with agile culture. Business critical applications have become so complex and demand for functionality so immediate that human-based quality practices are no longer sufficient. Developer capabilities must be enhanced by system-level analysis of structural weaknesses and operational risks enabled by structural quality technology and measurement standards supported in DevOps toolchains. Empirical results will be reported from research on how some of the most severe Security and Reliability flaws are distributed in business applications. Recent results from machine learning research in structural quality will be discussed along with some caveats about what to expect. International standards for measuring the structural quality of software developed by the Consortium for IT Software Quality (CISQ) that supplement ISO 25023 will be reviewed. The talk concludes with organizational requirements for successfully adopting these advances.

CS Colloquium: Mohammad Soleymani (USC-ICT) - What Do Machines Learn in Emotion Recognition from EEG Signals?
Thu, Oct 04, 2018 @ 11:00 AM - 12:00 PM
Computer Science
Conferences, Lectures, & Seminars
Speaker: Mohammed Soleymani, USC-ICT
Talk Title: What Do Machines Learn in Emotion Recognition from EEG Signals?
Series: CS Colloquium
Abstract: Machines that are able to read our emotions and cognitive states make better companions. Emotions are often sensed by their external manifestations such as facial and vocal expressions. Additionally, studies in affective neuroscience have identified a set of emotional neural activities that can be captured by eletroencephalogram (EEG) signals, including asymmetric frontal brain activity and increase in information transfer. Motivated by these findings, a growing number of studies report developing EEG-based emotion recognition systems with promising results. In this talk, I first present my work on recognizing emotions of people watching videos. I then present a follow up study in which we aimed to better understand what machine learns in such scenarios. In the follow up work, we recorded a dataset which includes spontaneous emotions and posed expressions. Our analysis on the data collected in the follow up study demonstrates that the performance of existing EEG-based emotion recognition methods significantly decreases when evaluated across different corpora. We also found that models trained on spontaneous emotions perform well on recognizing mimicked expressions. Our results provide evidence that stimuli-related sensory information and facial electromyogram activities are the main components learned by machine learning models for emotion recognition using EEG signals.

Information Sciences Institute
Conferences, Lectures, & Seminars
Speaker: Siva Reddy , Stanford University
Talk Title: CoQA: A Conversational Question Answering Challenge
Series: Natural Language Seminar
Abstract: Humans gather information by engaging in conversations involving a series of interconnected questions and answers. For machines to assist in information gathering, it is therefore essential to enable them to answer conversational questions. In this talk, I will present our work on CoQA, a novel dataset for building Conversational Question Answering systems. CoQA contains 127k questions with answers, obtained from 8k conversations about text passages from seven diverse domains. The questions are conversational, and the answers are free-form text with their corresponding evidence highlighted in the passage. We analyze CoQA in depth and show that conversational questions have challenging phenomena not present in existing reading comprehension datasets, e.g., coreference and pragmatic reasoning. We evaluate strong conversational and reading comprehension models on CoQA. The best system obtains an F1 score of 65.1%, which is 23.7 points behind human performance 88.8 percent, indicating there is ample room for improvement. We launch CoQA as a challenge to the community. See link below.
Biography: Siva Reddy is a postdoc in Computer Science at Stanford University working with Prof. Christopher Manning.

Ming Hsieh Department of Electrical Engineering
Conferences, Lectures, & Seminars
Speaker: Yu Hua, Huazhong University of Science and Technology
Talk Title: Encrypted Non-volatile Main Memory Systems
Abstract: Non-volatile memory (NVM) technologies are considered as promising candidates of the next-generation main memory. However, the non-volatility of NVMs leads to new security vulnerabilities. Memory encryption can be employed to mitigate the security vulnerabilities, but it increases the number of bits written to NVMs due to the diffusion property and thereby aggravates the NVM wear-out induced by writes. To address these security and endurance challenges, we propose DeWrite, a secure and deduplication-aware scheme to enhance the performance and endurance of encrypted NVMs based on a new in-line deduplication technique and the synergistic integrations of deduplication and memory encryption. Specifically, it performs low-latency in-line deduplication to exploit the abundant cache-line-level duplications leveraging the intrinsic read/write asymmetry of NVMs and light-weight hashing. It also opportunistically parallelizes the operations of deduplication and encryption and allows them to co-locate the metadata for high efficiency. DeWrite was implemented on the gem5 with NVMain.
Biography: Dr. Yu Hua is a professor in Huazhong University of Science and Technology. He was Postdoc Research Associate in McGill University in 2009, and Postdoc Research Fellow in University of Nebraska-Lincoln in 2010-2011.

Farewell to Servers: Hardware, Software, and Network Approaches towards Datacenter Resource Disaggregation
Fri, Oct 05, 2018 @ 10:00 AM - 11:00 AM
Ming Hsieh Department of Electrical Engineering
Conferences, Lectures, & Seminars
Speaker: Yiying Zhang, Purdue University
Talk Title: Farewell to Servers: Hardware, Software, and Network Approaches towards Datacenter Resource Disaggregation
Abstract: Datacenters have been using a "monolithic" server model for decades, where each server has a motherboard that hosts a set of hardware devices such as processors and memory chips. This monolithic architecture is easy to deploy but cannot fully support the growing hardware heterogeneity in datacenters or provide hardware elasticity, failure isolation, and efficient resource utilization. Going forward, we have to rethink the decade-long server-centric model.
Our answer is to break the monolithic server model into distributed, network-attached hardware components that can each manage its own resources and can fail independently. For the past three years, my lab has been working on such datacenter "resource disaggregation" at system software, networking, and hardware levels. In this talk, I will discuss our various efforts in building a disaggregated datacenter (or "DC-3.0"). Specifically, I will focus on two systems: LegoOS, a new distributed, disseminated OS designed for datacenter resource disaggregation (OSDI'18), and LITE, a Local Indirection TiEr in kernel to virtualize native RDMA into a flexible, high-level, easy-to-use abstraction (SOSP'17).
Biography: Yiying Zhang is an assistant professor in the School of Electrical and Computer Engineering at Purdue University. Her research interests span operating systems, distributed systems, datacenter networking, and computer architecture, with a focus on building software, hardware, network systems for next-generation datacenters. Her lab is pioneering in the field of datacenter resource disaggregation and is among the few groups in the world that builds new OSes and full-stack, cross-layer systems. She has published at and served on the program committees of top systems conferences such as SOSP, OSDI, and ASPLOS, and her work has attracted various industry and academia attentions. Yiying received her Ph.D. from the Department of Computer Sciences at the University of Wisconsin-Madison and worked as a postdoctoral scholar at the University of California, San Diego before joining Purdue.

Talk Title: Laboratory to Market: University Technology Licensing
Abstract: Abstract: A discussion of today's knowledge society, role of universities, specifics of Stanford's experience, cultural and other impediments to innovation, university policies, and elements of a university technology licensing office.
Biography: Biography: Niels Founded and directed Stanford Office of Technology Licensing, 1968-91. During the 22 years he managed the program at Stanford, he was loaned to Massachusetts Institute of Technology to reform its program, and to the University of California, Berkeley to found its program.
Cumulative licensing income to Stanford from an outside management firm, from 1954-67, totaled about $4,500. Niels proposed a pilot year-long licensing office with a marketing focus, which pilot year (1968-69) achieved $55,000 in licensing income. A permanent office then was approved, with a staff of Niels and a secretary/office manager. As the work load grew from increasing numbers of technology disclosures from faculty and students, staff were added. Cumulative licensing income from 1968 is expected to top $2 billion in fiscal year 2019.

Abstract: Finite abstractions of continuous dynamical systems play a central role in synthesizing controllers that enforce complex specifications, such as those expressed in temporal logic, and enable the designer to leverage tools from model checking and reactive synthesis. The resulting controller is symbolic, meaning that it only requires knowledge of quantized states that represent the currently occupied partition of the state space. Existing computational tools for this approach have been limited to small systems because both the abstraction and synthesis steps suffer from severe time and space bottlenecks as the system dimension grows. This talk will present recent results that overcome these bottlenecks by exploiting structural system properties. These results include: (1) taking advantage of monotonicity properties of the dynamical model for efficient reachability computations, (2) using sparsity structures in the dependency graph of state variables for parsimonious abstraction algorithms that dramatically reduce runtime, and (3) dividing the control synthesis task into sub-problems of manageable size with compositional procedures. The results will be illustrated with several practically motivated examples.

Talk Title: Tracking down Software Vulnerabilities from Unexpected Crashes
Series: Computer Science Colloquium
Abstract: Despite the best efforts of developers, software inevitably contains flaws that may be leveraged as security vulnerabilities. Modern operating systems integrate various security mechanisms to prevent software faults from being exploited. To bypass these defenses and hijack program execution, an attacker therefore needs to constantly mutate an exploit and make many attempts. While in their attempts, the exploit triggers a security vulnerability and makes the running process terminate abnormally.
After a program has crashed and terminated abnormally, it typically leaves behind a snapshot of its crashing state in the form of a core dump. While a core dump carries a large amount of information, which has long been used for software debugging, it barely serves as informative debugging aids in locating software faults, particularly memory corruption vulnerabilities. As such, previous research mainly seeks fully reproducible execution tracing to identify software vulnerabilities in crashes. However, such techniques are usually impractical for complex programs. Even for simple programs, the overhead of fully reproducible tracing may only be acceptable at the time of in-house testing.
In this talk, I will introduce a reverse execution technique, which takes as input a core dump, reversely executes the corresponding crashing program and automatically pinpoints the root cause of the vulnerable site hidden behind the crash. In the process of performing reverse execution, our technique typically encounters uncertainty (e.g., uncertain control or data flow) which significantly influence the capability of identifying vulnerabilities. Therefore, as part of the talk, I will also briefly discuss how we utilize deep recurrent neural network to tackle this technical challenge.
This lecture satisfies requirements for CSCI 591: Research Colloquium.

Talk Title: Talk1: Combining Active learning optimization and Temporal logic for parameter synthesis and falsification of Complex Systems Talk 2: System Design of Stochastic Models using Robustness of Temporal Properties
Series: Computer Science Colloquium jointly with CCI-MHI Cyber-Physical Systems Seminar
Abstract: We are pleased to announce two talks during this colloquium.
Talk 1: Combining Active learning optimization and Temporal logic for parameter synthesis and falsification of Complex Systems
In this talk, we discuss the combination of Active Learning Optimization and temporal logic to the falsification and parameter synthesis of complex dynamical systems. First, we introduce Gaussian Processes and an active learning approach aimed to falsify a black box model with time-dependent functional inputs. Second, we introduce a technique also base on Gaussian Processes, named Smoothed Model Checking, which is able to estimate the probability that a stochastic system satisfies a temporal logic formula. We leverage this estimation ability and an active learning approach to find regions of the parameter space where the model satisfies a temporal logic formula with probability greater (or less) than a given threshold.
Talk 2: System Design of Stochastic Models using Robustness of Temporal Properties
In the last years, researchers from the verification community have proposed several notions of robustness for temporal logic providing suitable definitions of distance between a trajectory of a (deterministic) dynamical system and the boundaries of the set of trajectories satisfying the property of interest. In this talk, we present an extension of this notion of robustness to stochastic systems, showing that this naturally leads to a distribution of robustness degrees. Then, we show how to exploit this notion to address the system design problem, where the goal is to optimise some control parameters of a stochastic model in order to maximise robustness of the desired specifications. The key idea is to use a learning algorithm to estimate the dependence of the average robustness of a qualitative formula over the model parameters. A powerful and provably convergent machine learning method, namely the Gaussian Process - Upper Confidence Bound (GP-UCB) algorithm is use to improve the parameter optimisation. Finally, we demonstrate the applicability of our method on a number of case studies and ongoing works.
This lecture satisfies requirements for CSCI 591: Research Colloquium. Please note, due to limited capacity in OHE 100D, seats will be first come first serve.

Multimodal Emotion Recognition: Quantifying Dynamics and Structure in Audio-Visual Expressive Speech

Conferences, Lectures, & Seminars
Speaker: Yelin (Lynn) Kim, Ph.D., Assistant Professor, University at Albany, SUNY
Talk Title: Multimodal Emotion Recognition: Quantifying Dynamics and Structure in Audio-Visual Expressive Speech
Abstract: The rise of AI assistant systems, including Google Home, Apple Siri, and Amazon Echo, brings the urgent need for increased and deeper understanding of users. In this talk, I will present algorithmic and statistical methods for analyzing audio-visual human behavior, particularly focusing on emotional and social signals inferred from speech and facial expressions. These methods can provide emotional intelligence to AI systems. However, developing automatic emotion recognition systems is challenging since emotional expressions are complex, dynamic, inherently multimodal, and are entangled with other factors of modulation (e.g. speech generation and emphasis). I will present several algorithms to address these fundamental challenges in emotion recognition: (i) cross-modal modeling methods that capture and control for interactions between individual facial regions and speech using the Minimum Description Length (MDL) principle-based segmentation; (ii) localization and prediction of events with salient emotional behaviors using a max-margin optimization and dynamic programming; and (iii) temporal modeling methods to learn co-occurrence patterns between emotional behaviors and emotion label noise. These algorithms have enabled advancements in the modeling of audio-visual emotion recognition systems and increased the understanding of the underlying dynamic and multimodal structure of affective communication (e.g., cross-modal interaction, temporal structure, and inherent perceptual ambiguity).

Auto-Tuned Threading for OLDI Microservices
Thu, Oct 11, 2018 @ 02:00 PM - 03:00 PM
Ming Hsieh Department of Electrical Engineering
Conferences, Lectures, & Seminars
Speaker: Akshitha Sriraman, University of Michigan
Talk Title: Auto-Tuned Threading for OLDI Microservices
Abstract: Modern On-Line Data Intensive (OLDI) applications have evolved from monolithic systems to instead comprise numerous, distributed microservices interacting via Remote Procedure Calls (RPCs). Microservices face sub-ms RPC latency goals, much tighter than their monolithic ancestors that must meet >=100ms latency targets. Sub-ms-scale threading and on currency design effects as well as OS and network overheads that were once insignificant for such monoliths, can now come to dominate in the sub-ms-scale microservice regime. It is therefore vital to characterize the influence of threading design, OS, and network effects on microservices. Unfortunately, widely used academic data center benchmark suites are unsuitable to aid this characterization as they use monolithic rather than microservice architectures.
We first investigate how OS/network overheads impact microservice tail latency by developing a complete suite of microservices called mSuite that we use to facilitate our study. Our characterization reveals that the relationship between optimal OS/network parameters and service load is complex. Our primary finding is that non-optimal OS scheduler decisions can degrade microservice tail latency by up to ~87%.
Secondly, we investigate how threading design critically impacts microservice tail latency by developing a taxonomy of threading models -“ a structured understanding of the implications of how microservices manage concurrency and interact with RPC interfaces under wide-ranging loads. We develop mTune, a system that has two features: (1) a novel framework that abstracts threading model implementation from application code, and (2) a novel automatic load adaptation system that curtails microservice tail latency by exploiting inherent latency trade-offs revealed in our taxonomy to transition among threading models. We study mTune in the context of mSuite to demonstrate up to 1.9x tail latency improvements over static threading choices and state-of-the-art adaptation techniques.

Abstract: Over the past decade we have been working to develop functional and molecular imaging technologies for a variety of applications. A current focus is technologies capable of functional imaging of picometer scale vibrations in the ear. This collaboration with researchers in otolaryngology has led to several recent papers that contribute new understandings of inner ear function. These were enabled by our development of Optical Coherence Tomography (OCT) as a highly sensitive spatially resolved vibrometer. Building on this approach, we have begun to develop devices to fill unmet clinical needs for diagnosis and therapeutic guidance in humans. The first of those devices (cochleoscope) is an endoscopic OCT system designed to traverse the human ear canal and peer into the inner ear through the round window. This device would be used clinically to identify endolymphatic hydrops, anomalous vibratory response, and ischemia of the inner ear. We recently demonstrated this device in a porcine model and have IRB approval for a first-in-human trial at USC. A second device attaches to the standard operating microscopes in the hearing clinic, enabling noninvasive imaging of middle ear morphology and function. In vivo human testing of this device has shown that we can achieve a sensitivity to vibrations of of

Talk Title: Optical Thermodynamics of Nonlinear Highly Multimode Systems
Abstract: The past few years have witnessed a resurgence of interest in multimode waveguide structures, predominantly driven by the ever-increasing demand for higher information capacities. This renaissance, in turn, incited a flurry of activities in the general area of nonlinear multimode fiber optics. The sheer complexity associated with the presence of hundreds or thousands of nonlinearly interacting modes that collectively act as a many-body system, has led to new opportunities in observing a multitude of novel optical effects that would have been otherwise impossible in single-mode settings. In this talk, a thermodynamic theory capable of describing complex, highly multimoded, nonlinear optical systems is presented. It is shown that the mode occupancies in such nonlinear multimode arrangements follow a universal behavior that always tends to maximize the system's entropy at steady-state. This thermodynamic response takes place irrespective of the type of nonlinearities involved and can be utilized to either heat or cool an optical multimode system. Aspects associated with adiabatic compressions and expansions will be discussed along with the possibility for all-optical Carnot cycles.

In this talk, I'll discuss general theoretical foundations for how to use such devices to demonstrate quantum supremacy: that is, a clear quantum speedup for some task, motivated by the goal of overturning the Extended Church-Turing Thesis (which says that all physical systems can be efficiently simulated by classical computers) as confidently
as possible. This part of the talk is based on joint work with Lijie
Chen. Then, in a second part, I'll discuss new, not-yet-published work on how these experiments could be used to generate cryptographically certified random bits, for use in cryptocurrencies and other applications.

Speaker: Ndapa Nakashole, UCSD
Talk Title: Mapping Functions for Multilingual Word Embeddings
Series: Natural Language Seminar
Abstract: Inducing multilingual word embeddings by learning a linear map between embedding spaces of different languages achieves remarkable accuracy on related languages. However, accuracy drops substantially when translating between distant languages. Given that languages exhibit differences in vocabulary, grammar, written form, or syntax, one would expect that embedding spaces of different languages have different structures especially for distant languages. I will present our work on understanding the behavior of linear maps learned by word translation methods. Additionally, I will present some initial solutions to the shortcomings of such linear maps.

Talk Title: Understanding Plug-and-Play ADMM: Convergence, Objective Function, and Generalization
Abstract: The Plug-and-Play (PnP) ADMM algorithm is a recently developed image restoration method that allows advanced image denoisers to be integrated into physical forward models to yield a provable convergent algorithm. Since its introduction in 2013, PnP ADMM has enabled numerous record-breaking image recovery results in deblurring, inpainting, super-resolution, Poisson denoising, and compressed sensing, etc. However, despite the successful applications and promising results, very little is known about why PnP ADMM performs so well. Fundamentally, the challenge lies in the fact that many of the latest denoisers are not easily expressible as proximal maps, e.g., deep neural networks.
In this talk, I will highlight a few recent progresses made by my group and collaborators. I will discuss three questions. (1) Convergence: Under what conditions of the denoisers will PnP ADMM converge? Answering this question will allow us to comment on what kind of denoisers we can use and what kind of convergence we should expect. (2) Objective Function: By plugging in an off-the-shelf denoiser, what does PnP ADMM actually solve? That is, what is the corresponding objective function? This problem will tell us why and when PnP ADMM will perform well, and when PnP ADMM will fail. (3) Generalization: Are we able to generalize PnP ADMM to accommodate multiple agents beyond a single forward model and a single denoiser? This leads to a new concept called consensus equilibrium, which allows us to integrate multiple weak experts to produce an overall strong recovery method. I will illustrate the ideas through examples in image denoising, graph signal processing, turbulence removal and automatic foreground extraction.

Speaker: Arya Mazumdar, College of Information & Computer Sciences, University of Massachusetts Amherst
Talk Title: Finding Structure in Data: Clustering and Representation Learning
Abstract: This talk is loosely divided into two parts, both about uncovering hidden structures in data by unsupervised or semisupervised methods. In the first, we discuss new tools to learn parameters of mixtures of distributions, statistical block models, and interactive algorithms for such problems. In the second, we describe new algorithms to learn nonlinear models of data, primarily focusing on networks of rectified linear units. We will emphasize on the information theoretic tools that have been used in both of the parts. We provide rigorous theoretical guarantees and our algorithms perform very well in experiments conducted with real data.

Talk Title: Topological Heterostructures by Molecular Beam Epitaxy
Abstract: Topology, both in real space and in reciprocal space, has emerged as a new design principle for materials that can host a wealth of novel properties. Interfaces and heterostructures with topological materials offer opportunities to control and manipulate their electronic states and associated phenomena, for example, via electric field effect, strain, or symmetry breaking. In this presentation, we will discuss recent progress in the growth of thin films of the three-dimensional Dirac semimetal Cd3As2 by molecular beam epitaxy. We show that high-mobility, epitaxial Cd3As2 films can be grown and discuss some of the phenomena that can be observed, such as an unusually large negative longitudinal magnetoresistance under parallel electric and magnetic fields. The heterostructures allow for experimental tests of theoretically predicted transitions between topological states by manipulating parameters, such as confinement and film strain. For example, as the film thickness is reduced, a band gap opens in the bulk Dirac electronic states and we observe a quantum Hall effect. Using electric field gating and Landau level spectroscopy, we demonstrate the Dirac dispersion of these two-dimensional states.

Conferences, Lectures, & Seminars
Speaker: Tara Javidi, Electrical and Computer Engineering, UC San Diego
Talk Title: Machine-Integrated Intelligence, Controlled Sensing, and Active Learning
Series: Center for Cyber-Physical Systems and Internet of Things
Abstract: The computing landscape has been drastically changing. The new computing realm, which is sometimes dubbed as internet of everything, includes networked devices ranging from tiny wearable sensors, smart home appliances, and personal autonomous robots, to connected self-driving cars, and to smart city infrastructures. In this new computing eco-system, comprising of resource-constrained, unreliable, and vulnerable components and networks, the non-recurring cost of hardware acceleration, engineering implementation, and system building has continued to grow significantly. This is in addition to the growing cost associated with the collection, curation, and labeling of data during both the training and the execution of various popular machine learning models. These design bottle-necks not only result in a significant increase in the non-recurring cost of engineering for companies but also provide a severe hurdle in technology development associated with hardware upgrade and/or system redesign.
In the first part of the talk, I will discuss an overview of my research on information acquisition and active learning in the context of the mission of our newly formed UCSD Center for Machine-Integrated Computing and Security (MICS). I will report ongoing research in the center where this system integrated view has enabled best-in-class results by bringing Machine into Machine Learning. In the second part of the talk, I will delve deeper into the problems of information acquisition, controlled sensing, and active learning and show our solutions to significantly reduce the cost of data collection and/or data labeling while ensuring reliability and fidelity during the training or run-time. In particular, we illustrate our findings and algorithms in the context of DetecDrone: an ML-enabled drone intelligence platform developed in my lab to provide search, mapping, and monitoring off-the-shelf low cost drones.
Biography: Tara Javidi studied electrical engineering at Sharif University of Technology, Tehran, Iran from 1992 to 1996. She received her MS degrees in electrical engineering (systems) and in applied mathematics (stochastic analysis) from the University of Michigan, Ann Arbor, in 1998 and 1999, respectively. She received her Ph.D. in electrical engineering and computer science from the University of Michigan, Ann Arbor, in 2002. From 2002 to 2004, Tara Javidi was an assistant professor at the Electrical Engineering Department, University of Washington, Seattle. In 2005, she joined the University of California, San Diego, where she is currently a professor of electrical and computer engineering and a founding co-director of the Center for Machine-aware Computing and Security (MICS).

Speaker: Fred Morstatter, USC - ISI
Talk Title: Discovering, Mitigating and Characterizing Social Data Bias
Series: CS Colloquium
Abstract: Researchers and practitioners use social media to extract actionable patterns about human behavior. However, biases are inevitable and can either be a hindrance or an asset to such analysis. In this talk, I will discuss perturbations to the underlying data that can lead to flawed analysis. I will show how common assumptions in handling social media data can lead to flawed research results, and suggest approaches to combat these problems. However, if we understand the biases in our dataset it can lead to deeper understanding of the populations we wish to study. Once the biases underlying a social dataset are recognized, researchers are in a better position to study the unique characteristics underlying different cultural groups. This talk will conclude with a discussion of ways to identify cultural groups online and to characterize the biases between them.
This lecture satisfies requirements for CSCI 591: Research Colloquium. Please note, due to limited capacity, seats will be first come first serve.
Biography: Fred Morstatter is a Computer Scientist at the Information Science Institute. His research focuses on understanding biases that occur in online social data.

Integrating Security in Cyber-physical Systems

Speaker: Miroslav Pajic, Duke University
Talk Title: : Integrating Security in Cyber-physical Systems
Series: Center for Cyber-Physical Systems and Internet of Things
Abstract: Modern embedded control architectures have moved from isolated systems to open architectures, such as new automotive systems with services that include remote diagnostics, code updates, and vehicle-to-vehicle communication. However, this increasing set of functionalities, network interoperability, and system design complexity have also introduced security vulnerabilities that are easily exploitable, since current embedded and cyber-physical systems have not been built with security in mind. Furthermore, the tight interaction between information technology and physical world makes these systems vulnerable to malicious attacks beyond the standard cyber-attacks, while relying exclusively on conventional security techniques may be unfeasible due to resource-constraints and long system lifetime.
Consequently, there is a need to change the way we reason about security in cyber-physical systems, and start designing platform-aware attack-resilient components and architectures capable of dealing with various attacks on the systems and its environment. In this talk, I will present our recent efforts in this domain, starting from cyber-physical security techniques that (a) capture effects of attacks on system performance, (b) introduce attack resilience into control algorithms and facilitate attack detection, and (c) enable mapping of the desired Quality-of-Control (QoC) under attack guarantees into real-time performance requirements on the underlying OS and networks. In addition, I will introduce a physics-aware design framework for securing resource-constrained CPS, that supports design-time tradeoffs between QoC in the presence of attacks and system resources used by the deployed security mechanisms, such as message authentication. This design framework has been used to add strong security guarantees in several existing automotive system. Finally, for systems with varying levels of autonomy and human interaction, I will show how we can exploit human power of inductive reasoning and the ability to provide context, to improve the overall security guarantees

Speaker: Dr. Xiang Ren, USC
Talk Title: Learning Text Structures with Weak Supervision
Series: USC Center for Artificial Intelligence in Society (CAIS) Seminar Series
Abstract: The real-world data, though massive, are hard for machines to resolve as they are largely unstructured and in the form of natural-language text. One of the grand challenges is to turn such massive corpora into machine-actionable structures. Yet, most existing systems have heavy reliance on human effort in the process of structuring various corpora, slowing down the development of downstream applications. In this talk, I will introduce an effort-light framework that extracts structured facts from massive corpora without task-specific human labeling effort. I will briefly introduce several interesting learning frameworks for structure extraction, and will share some directions towards mining corpus-specific structured networks for knowledge discovery.

MASCLE Machine Learning Seminar: Quanquan Gu (UCLA) - New Variance Reduction Algorithms for Nonconvex Finite-Sum Optimization

Computer Science
Conferences, Lectures, & Seminars
Speaker: Quanquan Gu, UCLA
Talk Title: New Variance Reduction Algorithms for Nonconvex Finite-Sum Optimization
Series: Machine Learning Seminar Series
Abstract: Nonconvex finite-sum optimization problems are ubiquitous in machine learning such as training deep neural networks. To solve this class of problems, various variance reduction based stochastic optimization algorithms have been proposed, which are guaranteed to converge to stationary points and enjoy improved gradient complexity than vanilla stochastic gradient descent. An natural question is whether there is still space for improvement to further speed up the finding of first-order stationary points and even local minimas.
In the first part of this talk, I will introduce our work for finding first-order stationary points in nonconvex finite-sum optimization that further pushes the frontiers of this line of research. In particular, I will introduce a new stochastic nested variance reduced gradient algorithm (SNVRG) that achieves the fastest convergence rate to first-order stationary points in the literature by reducing the variance in stochastic algorithms through multiple referencing points and gradients. It outperforms the folklore variance reduction methods such as stochastic variance reduced gradient (SVRG) and stochastically controlled stochastic gradient (SCSG).
In the second part of the talk, I will talk about methods for finding second-order stationary points (i.e., local minima) in nonconvex finite-sum optimization. Specifically, I will introduce a stochastic variance reduced cubic regularization algorithm that achieves the state-of-the-art second-order oracle complexity for finding local minima in nonconvex optimization.

Abstract: Modern electronics has been heavily relied on the technology to confine electrons in the interface layers of semiconductors. In recent years, scientists discovered that various atomically thin materials including graphene, a single atomic carbon layer, can be isolated. In these atomically thin materials, quantum physics allows electrons to move only in an effective 2-dimensional (2D) space. By stacking these 2D quantum materials, one can also create atomic-scale heterostructures with a wide variety of electronic and optical properties. I will discuss the creation of new heterostructures based on atomically thin materials and emerging new physics with technological implications therein.

Talk Title: Resilient Distributed Inference in Cyber-Physical Systems
Series: Center for Cyber-Physical Systems and Internet of Things
Abstract: In applications such as large-scale cyber-physical systems (CPS) and Internet-of-Things (IoT), as the number of devices or agents continues to grow, the integrity and trustworthiness of data generated by these devices becomes a pressing issue of paramount importance. An adversary may hijack individual devices or the communication channel between devices to maliciously alter data streams. In numerous IoT applications, we deploy physical devices throughout an environment, and we are interested in using the stream of sensor measurements to make inferences about the environmental state. Due to the large-scale and distributed nature of devices and data it might be infeasible to carry out computation and decision-making in a classical centralized fashion as well as to prevent attacks and intrusions on all data sources. As a result, reactive countermeasures, such as intrusion detection schemes and resilient inference algorithms become a vital component of security in distributed IoT-type setups.
As an alternative to traditional fusion-center based cloud setups, in this talk we focus on fog-type architectures in which devices themselves perform the necessary computations using local data and peer-to-peer information exchange with neighboring devices to make inferences about an environment. In the first part of the talk, we review distributed inference approaches and algorithms based on the consensus+innovations paradigm. We discuss performance metrics such as rates of convergence, communication complexity, and optimality. The second part of the talk focuses on recent work on secure and resilient variants of these algorithms in adversarial environments. Specifically, focusing on the case of data integrity attacks on the device network, we characterize fundamental trade-offs between resilience, quantified in terms of achievable inference performance and ability to detect intrusions and threats, and model properties such as observability and connectivity of the inter-device communication network.
