Multistage Mean-Variance Portfolio Selection in Cointegrated Vector Autoregressive Systems
Fri, Jan 23, 2009 @ 03:30 PM - 04:30 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Charlie Rohrs
Massachusetts Institute of TechnologyBased on the PhD work of
Melanie B. RudoyAbstract: Certain combinations of security prices reveal small amounts of intertemporal predictability when modeled as Cointegrated Vector Autoregressive Systems (CVAR). Such predictability can be exploited using tools from dynamic programming and optimal control theory to produce profitable portfolio optimization schemes. Here we use a standard Markowitz optimal mean variance approach on such systems. Certain CVAR systems display converging variance with increasing time horizon and we show how to appropriate exploit this phenomena when a single portfolio with no rebalancing throughout time is required. When rebalancing is allowed, the mean reversion properties of certain CVAR systems allow extra leveraging in intermediate stages to create higher profits. The extra leveraging produces excess profits while the variance trend is reversed by the terminal time to meet the overall variance constraint. The terminal time mean-variance problem does not quite fit with the CVAR models and an approximate solution is proposed.Biography: Charlie Rohrs received his BS degree from Notre Dame in 1976 and his Masters and PhD from MIT in 1978 and 1982 respectively. He served on the faculty at the University of Notre Dame from 1982 until 1997 and a Visiting Professor at MIT from 1997 until 2000. Charlie spent much of his career at The Tellabs Research Center, the research arm of Tellabs Operations, Inc., a manufacturer of telecommunications equipment for public service network providers. From 1985 until 1995, Dr. Rohrs was Director of the Research for Tellabs as the company grew from sales in the tens of millions to over a billion dollars annually. In 1995, he became the first Tellabs Fellow. Since 2001, Charlie has worked at MIT, first as a Principal Research Scientist in the Laboratory for Information and Decision Systems (LIDS) and then in his current position in the DSP group in RLE. While Dr. Rohrs is best known for his early contributions to the study of robustness in adaptive control, he has also contributed work in adaptive control, adaptive signal processing, communication theory, and communication networks and switching systems. He has recently become interested in the problems of financial engineering.Host: Michael Neely, mjneely@usc.edu, EEB 520, x03505

The Science and Technology of a Virtual Tutor: How Baldi Came to Be
Mon, Jan 26, 2009 @ 10:00 AM - 12:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Abstract:
Speech and language science and technology evolved under the assumption that speech was a solely auditory event. However, a burgeoning record of research findings reveals that our perception and understanding are
influenced by a speaker's face and accompanying gestures, as well as the actual sound of the speech. Perceivers expertly use these multiple sources of information to identify and interpret the language input. This behavior is
accurately described by our Fuzzy Logical Model of Perception. Extant issues in the processing of auditory and visual speech will be addressed. Given the value of face-to-face interaction and theoretical framework, our persistent goal has been to develop, evaluate, and apply animated agents to produce realistic and accurate speech. Baldi is an accurate three-dimensional animated talking head appropriately aligned with either synthesized or natural speech. Baldi has a realistic tongue and palate, which can be displayed by making his skin transparent.Based on this research and technology, we have implemented computer-assisted speech and language tutors for children with language challenges and persons learning a second language. Our language-training program utilizes Baldi as the conversational agent, who guides students through a variety of exercises designed to teach vocabulary and grammar, to improve speech articulation, and to develop linguistic and phonological awareness. Some of the advantages of the Baldi pedagogy and technology include the popularity and effectiveness of computers and embodied conversational agents, the perpetual availability of the program, and individualized instruction. The science and technology of Baldi holds great promise in language learning, dialog, human-machine interaction, education, and edutainment.Bio:

Active CROW Slow-Light Structures: New Directions and Applications
Fri, Jan 30, 2009 @ 11:00 AM - 12:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Jacob (Koby) Scheuer
School of EE, Tel-Aviv University, IsraelAbstract: In recent years, much attention has been focused on the behavior of light propagation in coupled resonator optical waveguides (CROWs). Substantial decrease of the group velocity can be attained in such chip-size structures, leading to numerous potential applications such as optical delay lines, optical filters wavelength converters and optical rotation sensors. However, the performance of CROW based systems is largely limited by the quality factor (Q) of the resonators composing it. Noticeable slowing of light necessitates small coupling between the micro-resonators, which, in turn, induces high optical losses, making the structure impractical for any real-life application. While the fabrication of high Q structures has been demonstrated, the complexity, high costs and low yields of such methods make them unsuitable for large – scale, commercial endeavors. In this talk, I will present new approach for overcoming the cavity loss problem based on incorporating optical gain in the cavities. New schemes for manipulating optical information by trapping and releasing optical pulses propagating in an array of coupled semiconductor lasers will be presented and analyzed. The incorporation of gain will be also shown to provide an efficient tool for dynamically controlling the propagation of light pulses, paving the road for realizable packet switching, routing and optical memory applications.Biography: Jacob (Koby) Scheuer received Ph.D. degree in electrical engineering from the Technion—Israel Institute of Technology, Haifa, Israel, in 2001. He was a Chief Designer with Lambda Crossing—an optical component startup specializing in microring resonators for two years. Then, he joined the Center for the Physics of Information and the Department of Applied Physics, the California Institute of Technology, Pasadena, as a Research Associate. Currently, he is a Senior Lecturer with the School of Electrical Engineering, Tel-Aviv University, Israel. His research interests include nanophotonics, polymer optics, slow light, and secure communications.Host: Alan Willner, willner@usc.edu, EEB 538, x04664

Integrated Sys Seminar-Traveling Wave Si ICs for High-Speed Comm. (Prof. Jim Buckwalter, UCSD)
Fri, Jan 30, 2009 @ 02:00 PM - 03:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker - Prof. James Buckwalter (UCSD)Abstract:Traveling wave structures are appealing for high-speed (>40Gbs) and high-frequency (>60GHz) communication circuits implemented with highly-scaled CMOS/BiCMOS processes because of the reduced passive area required for broadband matching. Broadband millimeter traveling wave approaches are discussed in this talk and novel schemes for improving the performance of traveling wave structures are presented. First, trade-offs between traveling wave and lumped circuits are described and loss-compensation for equalized frequency response is presented. Second, a 30dB, W-Band cascaded constructive wave amplifier is discussed that sets new records for the achievable gain in a silicon technology. Finally, a 10dB, 102GHz amplifier is presented for broadband circuit applications.

Radiation Effects Challenges in Commercial-Density SRAMS
Fri, Jan 30, 2009 @ 02:00 PM - 03:30 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Abstract: The space electronics industry is at an interesting crossroads. The space electronics demand is not sufficient to continue to justify the costs of building radiation-hardened IC fabrication foundries, which have risen to the multi-billion dollar range for deep-submicron technologies. The main thrust of the Radiation-Hardened-by-Design (RHBD) research area is to use architecture, circuit design, and layout techniques to build chips that are radiation-tolerant by using commodity commercial foundry lines. Under the sponsorship of the DARPA RHBD program, our research group has fabricated two 64Kbit SRAM devices in IBM 90nm technology using such techniques. The test results show that our resulting designs perform well in radiation environments with regard to single-event effects (SEE) with little area and speed penalties. The results also show that increased leakage power induced by high total ionizing dose (TID) is negligible below TID levels of 300 KRads. Bio: Dr. Jeff Draper holds joint appointments at USC as a Research Assistant Professor in the Ming Hsieh Department of Electrical Engineering and Project Leader at Information Sciences Institute. In addition to the RHBD work described above, his group contributed to the architecture and VLSI implementation of the MONARCH chip in IBM 90nm technology, a 100M-gate chip containing 6 RISC processors, 12 MB of embedded DRAM, a polymorphic streaming computing fabric, and several external ports. This combination of elements offers over 64 GFLOPS of computing throughput with 60 GB/s of memory bandwidth. Prior to this work, Dr. Draper's group completed the development of a 56-million transistor processing-in-memory (PIM) chip using TSMC 0.18-micron technology for the DIVA project. Dr. Draper received a BS in Electrical Engineering from Texas A & M University and an MSE and PhD in Computer Engineering from the University of Texas at Austin. He has published over 70 papers on many aspects of computer architecture and VLSI. His research interests are resilient computing, radiation hardening by design, PIM architectures, networks-on-chip, and multi-core architectures.
