Speaker: Reetuparna Das, University of Michigan, Ann Arbor
Talk Title: Architecting Components for a 10 Billion Transistor Processor
Abstract: Soon we may have processors with over ten billion transistors organized into hundreds of cores delivering supercomputer-like TeraFlops performance. To unlock this performance potential, however, we need dramatic improvements in processor efficiency to stay within the strict power budget. A significant source of inefficiency in today's general-purpose processors is that they tend to expend equal resources to varied applications without accounting for their individual needs. In this talk, I will present two solutions to address such inefficiency in both core and un-core parts of the processor. Composite cores eliminate needless power expended by out-of-order cores for applications with little or easy to exploit instruction-level parallelism. Aergia on-chip network prioritizes packets of network-sensitive applications to attain significantly higher throughput. I will also briefly discuss our on-going research that seeks to move compute close to storage in order to attain orders of magnitude improvement in efficiency for Big Data applications.

Speaker: Yutaka Hori, Caltech
Talk Title: Biochemical Feedback Control Theory for Synthetic Biocircuits
Abstract: Recent technological advancements have enabled us to construct
artificial biochemical networks, or biocircuits, that produce desired
dynamic functions such as bistability, oscillations and logic gates by
assembling DNA parts. This technology allows for many potential
engineering and biomedical applications, including the production of
high-value molecules and energy, and the sensing of hazardous chemicals,
using the cellular machinery of microbes. Toward a systematic
engineering of complex biological systems, model-based biocircuit design
has been increasingly important in recent years.
Biography: In this talk, we present a novel control theoretic framework to
systematically model, analyze and design the dynamics of biochemical
circuits along with experimental results. We first propose a general
feedback model representation of nonlinear biochemical dynamics. The
proposed modeling framework narrows the class of nonlinear systems down
to the degree where it allows us to develop rigorous and systematic
theoretical tools. We provide analytic and algebraic methods for
stability analysis and oscillator synthesis using the structure of the
system. Then, the utility of the developed tools is demonstrated by
experimentally implementing biochemical oscillator circuits. Finally, we
briefly show extensions of the proposed framework and discuss future
works along with some preliminary results.

Talk Title: Secure state-estimation and control for dynamical systems under adversarial attacks
Series: CommNetS
Abstract: Control systems work silently in the background to support much of the critical infrastructure we have grown used to. Water distribution networks, sewer networks, gas and oil networks, and the power grid are just a few examples of critical infrastructure that rely on control systems for its normal operation. These systems are becoming increasingly networked both for distributed control and sensing, as well as for remote monitoring and reconfiguration. Unfortunately, once these systems become connected to the internet they become vulnerable to attacks that, although launched in the cyber domain, have for objective the manipulation of the physical domain. In this talk I will discuss the problem of state-estimation and control for linear dynamical systems when some of the sensor measurements are subject to an adversarial attack. I will show that a separation result holds so that controlling physical systems under active adversaries can be reduced to a state-estimation problem under active adversaries. I will characterize the maximal number of attacked sensors under which state estimation is possible and propose computationally feasible estimation algorithms. For this, I will use ideas from compressed sensing and error correction over the reals while exploiting the dynamical nature of the problem. Time permitting, I will also report on more recent results using satisfiability module theory solvers.

Trustworthy Integrated Circuit Design

Speaker: Jeyavijayan (JV) Rajendran, New York University
Talk Title: Trustworthy Integrated Circuit Design
Abstract: Designers use third-party intellectual property (IP) cores and outsource various steps in their integrated circuit (IC) design and manufacturing flow. As a result, security vulnerabilities have been emerging, forcing IC designers and end users to reevaluate their trust in ICs. If an attacker gets hold of an unprotected IC, attacks such as reverse engineering the IC and piracy are possible. Similarly, if an attacker gets hold of an unprotected design, insertion of malicious circuits in the design, and IP piracy are possible.â¨To thwart these and similar attacks, we have developed three defenses: IC camouflaging, logic encryption, and split manufacturing. IC camouflaging modifies the layout of certain gates in the IC to deceive attackers into obtaining an incorrect netlist, thereby, preventing reverse engineering by a malicious user. Logic encryption implements a built-in locking mechanism on ICs to prevent reverse engineering and IP piracy by a malicious foundry and user. Split manufacturing splits the layout and manufactures different metal layers in two separate foundries to prevent reverse engineering and piracy by a malicious foundry. We then describe how these techniques are enhanced by using existing IC testing principles, thereby leading to trustworthy ICs.

Speaker: Mohamed Mohamed, University of Illinois at Urbana-Champaign
Talk Title: A Coupled Multiphysics Approach to Modeling Heating in Semiconductor Devices
Abstract: It is estimated that world energy consumption will increase by over 40% from 2012 to 2035. Meeting this energy demand while minimizing the proliferation of greenhouse gases and other toxins is one of societyâs key challenges. In recent years, thermal management has emerged as the ultimate bottleneck for improving the performance of consumer/commercial electronics. Controlling device temperature, as well as harnessing waste heat, is crucial to sustaining electronic devices with longer battery life and performance, in addition to potentially reducing our demand on power plants by efficiently using generated electricity. Without proper thermal management, inordinate power dissipation can potentially halt integrated circuit functionality.
For this reason, the development of state-of-the-art simulation models that self-consistently couple the electronic and phonon transport is essential in creating a cycle that pushes designs to have lower carbon footprints and creating environmentally conscious electronics that minimize waste. In this talk, I will highlight my work on electron and thermal transport and its relevance to nanoelectronic devices and materials. We will particularly address issues ranging from transport and modeling issues to power dissipation and energy harvesting. We will draw examples ranging from multi-gate FETs, SONOS memories, tunneling FETs and thermoelectric devices and suggest new directions for improving device efficiency through device and material engineering.

Speaker: Bhaskar D. Rao, University of California, San Diego
Talk Title: Hierarchical Bayesian Methods for Sparse Signal Recovery
Abstract: Compressive sensing (CS) as an approach for data acquisition has recently received much attention. In CS, the signal recovery problem from the observed data requires the solution of a sparse vector from an underdetermined system of equations. The underlying sparse signal recovery problem is quite general with many applications and is the focus of this talk. The main emphasis will be on a hierarchical Bayesian framework with a detailed discussion of an empirical Bayesian method, the Sparse Bayesian Learning (SBL) method. To develop this framework, priors modeled as scale mixtures of normal distributions will be discussed which include super-Gaussian and student-t priors as special cases. The talk will also discuss Bayesian methods for sparse recovery problems with structure; Intra-vector correlation in the context of the block sparse model and inter-vector correlation in the context of the multiple measurement vector problem.

Speaker: Hang-Phuc Le, Lion Semiconductor Inc., CA
Talk Title: Integrated Power Supply Design - Itâs Time to Work with the Load
Abstract: In order to meet the demand for processing performance required in electronic devices, parallelism have been used to increase throughput within a strict power constraint. As parallelism increases the number of cores integrated onto a chip, there are increasing need and benefit to utilizing an independent power supply for each core in order to optimize total chip power and circuit performance. Simply adding off-chip supplies will not only incur significant degradation of supply impedance due to split package power planes and a limited number of pins, but also additional cost due to increased motherboard size and package complexity.
To address these challenges, fully integrated power converters appeared to be the ultimate solution. I will present our design methodology and techniques for the switched-capacitor approach to achieve high power density, high efficiency and sub-ns transient response using standard CMOS processes. A new architecture of fully integrated hybrid converter will also be introduced.
At the end of the talk, I will discuss how integrated power supply can be designed to improve future system efficiency and performance in many applications ranging from building power distributions to the Internet of Things and implantable devices.

Control Mechanisms for Sustainable Power Systems: Risk management and Combinatorial Optimization

Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Insoon Yang, UC Berkeley
Talk Title: Control Mechanisms for Sustainable Power Systems: Risk management and Combinatorial Optimization
Abstract: To decarbonize the electric power grid, there have been increased efforts to utilize clean renewable energy sources, as well as demand-side resources such as electric loads. This utilization is challenging because of uncertain renewable generation and inelastic demand. Furthermore, the interdependencies between system states of power networks or interconnected loads complicate several decision-making problems. In this talk, I will present two control and optimization tools to help to overcome these challenges and improve the sustainability of electric power systems. The first tool is a new dynamic contract approach for direct or indirect load control that can manage the financial risks of utilities and customers, where the risks are generated by uncertain renewable generation. The key feature of the proposed contract method is its risk-limiting capability, which is achieved by formulating the contract design problem as mean-variance constrained risk-sensitive control. I will present a dynamical system approach to track and limit risks. The performance of the proposed contract framework is demonstrated using data from the Electricity Reliability Council of Texas. The second tool is developed for combinatorial decision-making under system interdependencies, which are inherent in interconnected loads and power networks. For such decision-making problems, which can be formulated as optimization of combinatorial dynamical systems, I will present a linear approximation method that is scalable and has a provable suboptimality bound. The performance of the approximation algorithm is illustrated in ON/OFF control of interconnected supermarket refrigeration systems and power network topology optimization. Finally, I will discuss several future research directions in the operation of sustainable cyber-physical systems, including a unified risk management framework for electricity markets, a selective optimal control mechanism for resilient power grids, and contract-based modular management of cyber-physical infrastructure networks.

Talk Title: Reconfigurable Mixed Signal Neuromorphic Architectures
Abstract: Many decades ago, Carver Mead established the foundations of neuromorphic systems. Neuromorphic systems are analog circuits that emulate biology. These circuits utilize subthreshold dynamics of CMOS transistors to mimic the behavior of neurons. The objective is to not only simulate the human brain, but also to build useful applications using these bio-inspired circuits for ultra low power speech processing, image processing, and robotics. This can be achieved using reconfigurable hardware, like field programmable analog arrays (FPAAs), which enable configuring different applications on a cross platform system. As digital systems saturate in terms of power efficiency, this alternate approach has the potential to improve computational efficiency by approximately eight orders of magnitude. These systems, which include analog, digital, and neuromorphic elements combine to result in a very powerful reconfigurable processing machine.

Talk Title: Monolayer Materials for Electronics
Abstract: In recent years, significant progress has been achieved in exploring electronics applications of two-dimensional monolayer materials. Monolayer represents the ultimate limit of body thickness in a transistor structure, and it is free from body thickness variability and interface dangling bonds. Its mechanical bendability promises interesting applications in flexible and wearable electronics. Furthermore, two-dimensional materials and their heterojunctions possess properties not available in their conventional semiconductor counterparts. To translate the new material properties to device technologies, device modeling and simulation play an important role in understanding experiments, assessing technology potential, and optimizing device designs.
In this talk, I will first overview the challenges of modeling electron devices made from nanomaterials. Two examples of devices based on two-dimensional semiconductors will then be highlighted. In the first one, anisotropic carrier transport in black phosphorene will be examined to understand their potential in logic and RF transistor applications. In the second example, device physics and design options of monolayer heterojunction photodiodes and tunneling field-effect transistors will be discussed, which promise ultra steep subthreshold swing and low power dissipation.

Talk Title: Vehicular Network: From Internet of Things to Urban Planning
Series: CommNetS
Abstract: With the advent of the new technological era, smart phones, web2, data sharing and video streaming are playing a major role in every ones daily life, the demand for data is increasing with an accelerating pace. This in turn requires more capable and complex technologies to support this uprising demand. LTE Advanced and Wi-Max Advanced are examples of these most recent commercial technological boosts that are categorized under true 4G. However, by the constant pace of data demand increase, lots of attention and literature focus have been turned into what need to be considered next. In order to further enhance the backbone capacity of data delivery, different schemes are suggested. Among all different approaches, vehicular networks are of great interest. They can provide a viable high capacity and low cost alternative for data delivery. They get more interesting when we bring in their ability to provide a sensing-net as well. This talk explores the ability of vehicular networks in these contexts and also focus on the ways that we can change the current traffic patterns into ones that could serve us better both on the application side as well as urban traffic standards.

Talk Title: When Logic Meets Physics: Compositional Design of Cyber-Physical Systems Using Contracts
Abstract: The realization of large and complex cyber-physical systems (such as âsmartâ transportation, energy, security, and health-care systems) is creating design and verification challenges, which will soon become insurmountable with the current engineering practices. In this talk, I introduce a design methodology that addresses the complexity and heterogeneity of these systems by using assume-guarantee contracts to formalize the design process and enable the realization of system architectures and control algorithms in a hierarchical and compositional way.
In the proposed methodology, the design is carried out as a sequence of refinement steps from a high-level specification to an implementation built out of a library of components at the lower level. Top-level system requirements are represented as contracts, by leveraging a set of formal languages, including mixed integer-linear constraints and temporal logic, to allow for requirement analysis and early detection of inconsistencies. Top-level contracts are then refined to achieve independent implementation of system architecture and control algorithm, by combining synthesis from requirements, optimization and simulation-based design space exploration methods. I show how key analysis tasks, such as refinement checking, can indeed be made more efficient when a system is described based on a pre-characterized library of components and contracts. Moreover, at the heart of the architecture design framework, I propose two optimization-based algorithms to tackle the exponential complexity of exact reliability computation, and enable scalable co-design of large, safety-critical systems for cost and fault tolerance.
I demonstrate, for the first time, the effectiveness of a contract-based approach on a real-life example of industrial relevance, namely the design of aircraft electric power distribution systems. I show that optimized selection of large, industrial-scale power system architectures can be performed in a few minutes, while design verification of controllers based on linear temporal logic contracts can achieve up to two orders of magnitude improvement in execution time with respect to conventional techniques. Finally, I conclude by presenting future research directions towards a full-fledged compositional framework for system design.

Speaker: Athanassios S. Fokas, PhD, MD, Department of Applied Mathematics and Theoretical Physics, University of Cambridge
Talk Title: Inverse Problems and the Importance of Unconscious Processes
Abstract: Mathematics provides a marvellous illustration of the innate ability of the brain to âlearnâ as well as to âcreateâ via the process of making associations and generalisations. This forms the basis of abstract thinking which indeed finds its apotheosis in mathematics. The discovery of a new method for solving partial differential equations (PDEs), which has been acclaimed as ââthe most important development in the analysis of PDEs since the work of Fourier in the 18th centuryâ, will be used as an illustrative example of the above process. This unexpected discovery is also related to recent progress in the analysis of certain inverse problems arising in medical imaging. The role of this development, as well as of mathematics in general, in elucidating the importance of unconscious processes will be discussed.
Biography: A.S. Fokas has a BSc in Aeronautics from Imperial College (1975), a PhD in Applied Mathematics from the California Institute of Technology (1979) and an MD from the University of Miami, School of Medicine (1986). In 1986 he was appointed Professor and Chairman of the Department of Mathematics and Computer Science of Clarkson University, USA. In 1996 he was appointed to a Chair in Applied Mathematics at Imperial College, UK. In 2002 he was appointed to the newly inaugurated Chair in Nonlinear Mathematical Science at the University of Cambridge, UK. In 2000 he was awarded the Naylor Prize, which is the most prestigious Prize in Applied Mathematics and Theoretical Physics in UK (the last earlier recipient was S.W. Hawking). He has also been awarded the Aristeion Prize in Sciences of the Academy of Athens which is the most important prize of the Academy given every four years to a single scholar of Greek origin, as well as the Excellence Prize of the Bodossaki Foundation which is the premier scientific prize in Greece. He has received honorary degrees from seven Universities and also has been decorated as the Commander of the Order of Phoenix by the President of the Hellenic Republic. In 2009 he was selected as a Guggenheim Fellow. He is a member of the European Academy of Sciences and he is the first ever Applied Mathematician to be elected a full member in the Academy of Athens. He is a Professorial Fellow at Clare Hall College, Cambridge. He is the author or co-author of three monographs and of more than 300 papers, as well as the co-editor of seven books.

Talk Title: Around the Reproducibility of Scientific Research: A Knockoff Filter for Controlling the False Discovery Rate
Abstract: The big data era has created a new scientific paradigm: collect data first, ask questions later. When the universe of scientific hypotheses that are being examined simultaneously is not taken account, inferences are likely to be false. The consequence is that follow up studies are likely not to be able to reproduce earlier reported findings or discoveries. This reproducibility failure bears a substantial cost and this talk is about new statistical tools to address this issue. Imagine that we observe a response variable together with a large number of potential explanatory variables, and would like to be able to discover which variables are truly associated with the response. At the same time, we need to know that the false discovery rate (FDR)---the expected fraction of false discoveries among all discoveries---is not too high, in order to assure the scientist that most of the discoveries are indeed true and replicable. We introduce the knockoff filter, a new variable selection procedure controlling the FDR in the statistical linear model whenever there are at least as many observations as variables. This method achieves exact FDR control in finite sample settings no matter the design or covariates, the number of variables in the model, and the amplitudes of the unknown regression coefficients, and does not require any knowledge of the noise level. This work is joint with Rina Foygel Barber.

Talk Title: Content Caching and Delivery: Fundamental Limits, Challenges, and Opportunities
Series: CommNetS
Abstract: Designing the infrastructure to handle massive amounts of data requires tools and techniques from different research areas including communication, computing, and storage. Each of these areas has different performance metrics such as rate, delay, storage and bandwidth costs. Traditionally, a subset of these metrics is studied in isolation within each research area. In this talk, we argue that these metrics should instead be analyzed jointly by characterizing the fundamental trade-offs between them.
In the first part of the talk, we focus on the fundamental trade-off between communication and storage in cache networks. The today's caching algorithms optimize the caches in order to maximize the amount of content delivered locally. We show that this approach is inefficient for cache networks. We introduce a new formulation of the caching problem, focusing on its basic structure. For this setting, we propose a novel coded caching approach that achieves significantly larger reduction in peak rate compared to previously known caching schemes. In particular, the improvement can be on the order of the number of caches in the network. This result leads to the first fundamental characterization of the rate-memory trade-off for systems with more than one cache.
In the second part of the talk, we shift focus to the interplay of network delay and communication rate. As a representative example, we consider the emerging application of offloading of base-band processing from wireless networks to the cloud. Network delay could prevent the use of traditional approaches of interference management such as cooperative interference cancellation and interference alignment. In this talk, we propose a new approach for interference management that achieves a rate close to cooperative schemes, but that is tolerant of even large delays.

Talk Title: Sufficient Statistics for Multi-Agent Decision
Series: CommNetS
Abstract: We describe a notion of sufficient statistics for decision, estimation or control problems involving multiple players. As in the classical single-player setting, sufficient statistics contain all of the information necessary for the players to make optimal decisions. In the multi-agent setting, we construct such sufficient statistics via a convex relaxation of the feasible set of the corresponding decision problem. We show that these statistics may be updated recursively, and may be constructed by appropriately composing the corresponding single-player statistics. We present algorithms for this construction when the information pattern is defined by an appropriate graph.
Biography: Sanjay Lall is Professor of Electrical Engineering at Stanford University. Previously he was a Research Fellow at the California Institute of Technology in the Department of Control and Dynamical Systems, and prior to that he was NATO Research Fellow at Massachusetts Institute of Technology, in the Laboratory for Information and Decision Systems.

Talk Title: Large Graph Mining: Patterns, Cascades, Fraud Detection, and Algorithms
Series: Energy Informatics Distinguished Seminar Series
Abstract: Given a large graph, like who-calls-whom, or who-likes-whom, what behavior is normal and what should be surprising, possibly due to fraudulent activity? How do graphs evolve over time? How does influence/news/viruses propagate, over time? We focus on three topics: (a) anomaly detection in large static graphs (b) patterns and anomalies in large time-evolving graphs and (c) cascades and immunization.
For the first, we present a list of static and temporal laws, including advances patterns like 'eigenspokes'; we show how to use them to spot suspicious activities, in on-line buyer-and-seller settings, in FaceBook, in twitter-like networks. For the second, we show how to handle time-evolving graphs as tensors, how to handle large tensors in map-reduce environments, as well as some discoveries such settings.
For the third, we show that for virus propagation, a single number is enough to characterize the connectivity of graph, and thus we show how to do efficient immunization for almost any type of virus (SIS - no immunity; SIR - lifetime immunity; etc)
We conclude with some open research questions for graph mining.

Talk Title: Revolutionizing Medical Device Design
Abstract: The vision of the MIT Medical Electronic Device Realization Center (MEDRC) is to revolutionize medical diagnostics and treatments by bringing health care directly to the individual and to create enabling technology for the future information-driven healthcare system. This vision will in turn transform the medical electronic device industry. Specific areas that show promise are wearable or minimally invasive monitoring devices, medical imaging, portable laboratory instrumentation, and the data communication from these devices and instruments to healthcare providers and caregivers.
Rapid innovation in miniaturization, mobility, and connectivity will revolutionize medical diagnostics and treatments, bringing health care directly to the individual. Continuous monitoring of physiological markers will place capability for the early detection and prevention of disease in the hands of the consumer, shifting to a paradigm of maintaining wellness rather than treating sickness. Just as the personal computer revolution has brought computation to the individual, this revolution in personal medicine will bring the hospital lab and the physician to the home, to emerging countries, and to emergency situations. These system solutions containing state-of-the-art sensors, electronics, and computation will radically change our approach to health care. This new generation of medical systems holds the promise of delivering better quality health care while reducing medical costs.
In this talk I will introduce the research directions of the MEDRC and discuss the circuit and system design issues and clinical measurements from selected MEDRC projects highlighting wearable monitoring.
