MULTIPLAYER GAMES AND ADAPTIVE CONVERGENCE TO NASH EQUILIBRIA

Professor Jeff ShammaMechanical and Aerospace Engineering Department
University of California, Los AngelesConsider a scenario in which multiple decision makers repeatedly play a matrix game and adjust their strategies according to observations of each other's actions. The game is noncooperative in that each player may have its own objective/utility function, and these objectives are not shared among players. A central issue is whether player strategies will converge to a Nash equilibrium. Prior work shows how convergence to a Nash equilibrium in this setting may or may not occur. This talk presents new strategic update mechanisms that can lead to convergent
behavior in previously nonconvergent cases (such as the Shapley and Jordan counterexamples) through the use of fundamental feedback control concepts. The talk also discusses implications regarding evolutionary game theory and population dynamics.----------------------------------------------------------- BIOGRAPHY Jeff S. Shamma is a Professor of Mechanical and Aerospace Engineering at the University of California, Los Angeles. He received the Ph.D. degree in Systems Science and Engineering in 1988 from the Massachusetts Institute of Technology, Department of Mechanical Engineering. He held
faculty positions at the University of Minnesota, Minneapolis, and the University of Texas, Austin, before joining UCLA in 1999. He is a recipient of a 1992 NSF Young Investigator Award and the 1996 Donald P. Eckman Award of the American Automatic Control Council, and was a Plenary Speaker at the 1998 American Control Conference. His main research interest is feedback control.--------------------------------Host: Professor Petros Ioannou ioannou@usc.eduLocation: Hughes Aircraft Electrical Engineering Center (EEB) - 248

"FPGA-BASED DATA-MINING ARCHITECTURES"Zachary BakerElectrical Engineering-SystemsAbstract:Recent advances in storage and data sensing have revolutionized our technological capability for collecting and storing data. The Apriori algorithm is a popular correlation-based data-mining kernel. However, it is a computationally expensive algorithm and the running times can stretch up to days for large databases, as database sizes can extend to Gigabytes. Through the use of a new extension to the systolic array architecture, time required for processing can be significantly reduced. Our array architecture implementation on a Xilinx Virtex-II Pro 100 provides a performance improvement that can be orders of magnitude faster than the state-of-the-art software implementations. The system is easily scalable and introduces an efficient ``systolic injection'' method for intelligently reporting unpredictably generated mid-array results to a controller without any chance of collision or excessive stalling.Bio:Zachary K.

"SOFTWARE DEFINED SIGNAL PROCESSING"Prof. Ryan KastnerUC, Santa BarbaraAbstract:The vision of ubiquitous connectivity is gradually becoming a reality with the development and deployment of cellular, Wi-Fi (802.11x) and even underwater wireless networks. However, many important challenges remain before true universal access is achieved. Among them is the development of hardware that can implement these increasingly complex communication protocols. Ideally, the hardware platform will provide a mechanism for multimode, multi-band, and multifunctional wireless communication. All the functions of this "software defined" communication device, except the front end of the receiver/transmitter (e.g. antenna and RF power amplifier), are implemented in changeable code. This requires an efficient and flexible high performance platform. The performance and flexibility of reconfigurable computing systems make them ideal platform for software defined signal processing. In order to realize a software-defined signal processing system, we must develop tools and methodologies to can automatically map communication protocols to hardware. In this talk, I will describe some of our research aimed at providing signal processing application designers with basic tools that allow them to quickly map their protocols into reconfigurable hardware. I will present a design flow from high level application specification to a bitstream that can be used to program a modern, high performance FPGA. Our design flow is unique in that it treats the FPGA as a two dimensional array of configurable data paths. As such, the distribution of the application data plays a large role in the performance of the application mapping. I will discuss our optimizations for partitioning data across the complex memory hierarchy seen in modern reconfigurable architectures. To motivate our design flow, I will discuss our recent work on implementing two signal processing applications on a high performance FPGA - radiolocation algorithms for RF (802.11x) and underwater acoustic modems.Bio:Ryan Kastner is currently an assistant professor in the Department of Electrical and Computer Engineering at the University of California, Santa Barbara. He received a PhD in Computer Science (2002) at UCLA, a masters degree in engineering (2000) and bachelor degrees (BS) in both electrical engineering and computer engineering (1999), all from Northwestern University. His current research interests lie in the realm of embedded systems, in particular reconfigurable computing, compilers and sensor networks. Professor Kastner has published close to 50 journal and conference papers, and is the author of the book, "Synthesis Techniques and Optimizations for Reconfigurable Systems" (with Majid Sarrafzadeh and Adam Kaplan), available from Kluwer Academic Publishing. He is a member of numerous conference technical committees including International Conference on Computer Aided Design (ICCAD), Design Automation Conference (DAC), International Conference on Computer Design (ICCD), Great Lakes Symposium on VLSI (GLSVLSI), the Engineering of Reconfigurable Systems and Algorithms (ERSA) and the IEEE International Symposium on Circuits and Systems (ISCAS). He serves on the editorial board for the Journal of Embedded Computing.Host: Prof. Viktor Prasanna, Ext. 04483
