  • CS Colloquium: Satish Kumar Thittamaranahalli (USC) – The Constraint Composite Graph and Its Applications

    Tue, Feb 27, 2018 @ 11:00 AM - 12:00 PM

    Thomas Lord Department of Computer Science

    Conferences, Lectures, & Seminars

    Speaker: Satish Kumar Thittamaranahalli, USC Information Sciences Institute

    Talk Title: The Constraint Composite Graph and Its Applications

    Series: Computer Science Colloquium

    Abstract: The weighted constraint satisfaction problem (WCSP) is a fundamental combinatorial problem with applications in such diverse areas as artificial intelligence, statistical physics, computer vision, and information theory. In this talk, I will present new methods for efficiently solving the WCSP. Central to these methods is the idea of the constraint composite graph (CCG). The CCG provides a unifying computational framework for simultaneously exploiting the structure of the variable-interactions in a given WCSP as well as the structure of the weighted constraints in it. I will present some important applications of the idea of the CCG in kernelization of combinatorial problems, the revival of message passing algorithms, and in other domains (if time permits).

    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.

    Biography: Dr. Satish Kumar Thittamaranahalli (T. K. Satish Kumar) leads the Collaboratory for Algorithmic Techniques and Artificial Intelligence at the Information Sciences Institute of the University of Southern California. He has published extensively on numerous topics in Artificial Intelligence spanning such diverse areas as Constraint Reasoning, Planning and Scheduling, Probabilistic Reasoning, Robotics, Combinatorial Optimization, Approximation and Randomization, Heuristic Search, Model-Based Reasoning, Knowledge Representation and Spatio-Temporal Reasoning. He has served on the Program Committees of many international conferences in Artificial Intelligence and is a winner of the 2016 Best Robotics Paper Award and the 2005 Best Student Paper Award from the International Conference on Automated Planning and Scheduling. Dr. Kumar received his PhD in Computer Science from Stanford University in March 2005. In the past, he has also been a Visiting Student at the NASA Ames Research Center, a Postdoctoral Research Scholar at the University of California, Berkeley, a Research Scientist at the Institute for Human and Machine Cognition, a Visiting Assistant Professor at the University of West Florida, and a Senior Research and Development Scientist at Mission Critical Technologies.

    Talk Title: Modern Automotive Vulnerabilities: Problems, Causes and Outcomes

    Series: Computer Science Keynote Series

    Abstract: Over the last six years, a range of research has transformed our understanding of automobiles. What we traditionally envisioned as mere mechanical conveyances are now more widely appreciated as complex distributed systems 'with wheels'. A car purchased today has virtually all aspects of its physical behavior mediated through dozens of microprocessors, themselves networked internally, and connected to a range of external digital channels. As a result, software vulnerabilities in automotive firmware potentially allow an adversary to obtain arbitrary control over the vehicle. Indeed, multiple research groups have been able to demonstrate such remote control of unmodified automobiles from a variety of manufacturers. In this talk, I'll highlight how our understanding of automotive security vulnerabilities has changed over time, how unique challenges in the automotive sector give rise to these problems and create non-intuitive constraints on their solutions and the key role played by the research community driving industry and government response.

    Biography: Stefan Savage is a professor of Computer Science and Engineering at the University of California, San Diego. He received his Ph.D. in Computer Science and Engineering from the University of Washington and a B.S. in Applied History from Carnegie Mellon University. Savage is a full-time empiricist, whose research interests lie at the intersection of computer security, distributed systems and networking. He currently serves as co-director of UCSD's Center for Network Systems (CNS) and for the Center for Evidence based Security Research (CESR). Savage is a MacArthur Fellow, a Sloan Fellow, an ACM Fellow, and is a recipient of the ACM Prize in Computing and the ACM SIGOPS Weiser Award. He currently holds the Irwin and Joan Jacobs Chair in Information and Computer Science, but is a fairly down-to-earth guy and only writes about himself in the third person when asked.
