CS Colloquium: Guy van den Broeck (KU Leuven) - Scalable Inference and Learning for High-Level Probabilistic Models
Thu, Apr 02, 2015 @ 09:45 AM - 10:50 AM
Thomas Lord Department of Computer Science

Speaker: Guy van den Broeck, KU Leuven
Talk Title: Scalable Inference and Learning for High-Level Probabilistic Models
Series: CS Colloquium
Abstract: Probabilistic graphical models are pervasive in AI and machine learning. A recent push, however, is towards more high-level representations of uncertainty, such as probabilistic programs, probabilistic databases, and statistical relational models. This move is akin to going from hardware circuits to a full-fledged programming language, and poses key challenges for inference and learning. For instance, we encounter a fundamental limitation of classical learning algorithms: they make strong independence assumptions about the entities in the data (e.g., images, web pages, patients, etc.). These assumptions fail to hold in a global view of the data, where all entities are related. We also encounter a limitation of existing reasoning algorithms, which fail to scale to large, densely connected graphical models, consisting of millions of interrelated entities.
In this talk, I present my research on efficient algorithms for high-level probabilistic models, called lifted inference and learning algorithms. I begin by introducing the key principles behind exact lifted inference, namely to exploit symmetry and exchangeability in the model. Next, I discuss the strengths and limitations of lifting. Building on results from database theory and counting complexity, I identify classes of tractable models, and classes where high-level reasoning is fundamentally hard. I conclude by showing the practical embodiment of these ideas, in the form of approximate inference and learning algorithms that scale up to big data and big models.
The lecture will be available to stream HERE

Trustworthy Integrated Circuit Design
Thu, Apr 02, 2015 @ 10:00 AM - 11:30 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
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.

EE-EP Seminar

Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
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.
Biography: Mohamed Mohamed received the Ph.D. degree in electrical engineering from the University of Illinois at Urbana-Champaign, Urbana, IL, USA, in 2012. He served as a Research Scientist and Visiting Lecturer with the University of Illinois at Urbana-Champaign. His doctoral dissertation work was performed in the Computational Multiscale Nanostructures group directed by Professor Umberto Ravaioli and has demonstrated self-heating effects in nanoscale silicon MOSFETs through coupled electro-thermal Monte Carlo simulation. His current research interest is primarily on the theory, design, simulation and characterization of energy efficient devices, materials and circuits. He also has a great interest in cyber education and in exploring innovative ways to enhance learning, education, and research. He has developed numerous simulation tools suitable for both research and classroom use hosted on the nanoHUB. He is the recipient of the Ernest Reid Fellowship Award in Electrical Engineering, the Graduate College Dean Fellowship and was listed several times in the UIUC List of Teachers Ranked Excellent.

Big Data and Data Science: Some Hype but Real Opportunities

Big Data and Data Science: Some Hype but Real Opportunities
IMSC Seminar – Host: Cyrus Shahabi
April 2 - 5:00-6:00pm
SAL-101
Speaker: Michael Franklin, UC Berkeley Computer Science
Abstract
Data is all the rage across industry and across campuses. While it may be temping to dismiss the buzz as just another spin of the hype cycle, there are substantial shifts and realignments underway that are fundamentally changing how Computer Science, Statistics and virtually all subject areas will be taught, researched, and perceived as disciplines. In this talk I will give my personal perspectives on this new landscape based on experiences organizing a large, industry-engaged academic Computer Science research project (the AMPLab), in helping to establish a campus-wide Data Science research initiative (the Berkeley Institute for Data Science), and my participation on a campus task force charged with mapping out Data Science Education for all undergraduates at Berkeley. I will make the case that there are real opportunities across campus in both education and research, and that Data Science should be viewed as an emerging discipline in its own right.
