CS Colloq: Dr. Pradeep Varakantham
Fri, May 07, 2010 @ 12:00 PM - 01:30 PM
Thomas Lord Department of Computer Science
Conferences, Lectures, & Seminars
Talk Title: Risk sensitive planning and scheduling in uncertain environmentsSpeaker: Dr. Pradeep VarakanthamHost: Prof. Milind TambeAbstract: In risk sensitive reasoning, the key goal is to maximize expected utility of a user as opposed to maximizing an expected value. Such reasoning is imperative in domains like financial planning, rescue scenarios and project scheduling problems, where users are involved and there is uncertainty associated with decisions. In this talk, I will motivate, present algorithms and show experimental results for risk sensitive reasoning in two different settings:
(a) Planning in partially observable domains with non-deterministic outcomes to actions: In this research, we consider different risk attitudes of users, which are modeled as non-linear utility functions (mapping from current wealth to the utility) and provide efficient mechanisms to compute policies that account for such risk attitudes;and
(b) Scheduling in resource constrained project scheduling problems with durational uncertainty: Here, we develop a fitness function that is based on a risk parameter set by users to guide search for robust schedules.Bio:Dr. Pradeep Varakantham is an assistant professor at Singapore Management University. Previously, he was a post doctoral fellow with Steve Smith in the Robotics Institute at Carnegie Mellon University. He received his PhD in Computer Science from University of Southern California under the guidance of Milind Tambe. His research interests include reasoning with uncertainty, multi agent systems, reinforcement/inverse learning and distributed constraint reasoning. He is co-author on a paper that was nominated for Jay Modi best student paper award at AAMAS 2009. He was the Outstanding Research Assistant in the Computer Science Department at University of Southern California for the year 2005. He has papers in some of the top Artificial Intelligence conferences including IJCAI, AAAI, AAMAS, and ICAPS.

Two Directions on Next Generation Video Coding Standard
Fri, May 07, 2010 @ 03:00 PM - 04:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Professor Wen Gao,
Peking UniversityAbstract:Video coding is one of the important technological advancements that have made a great difference to our lives. In the past decades, the development of efficient coding techniques has made a big contributes to industry, such as digital video, wireless or internet video, 3D video and so on, many techniques have been developed and evolved through several generations of video coding standards, e.g., MPEG-1/2/4, H.26x, VC-1, and AVS. The movement of developing next-generation video coding standard is just becoming hot, which provides the challenges and opportunities equally to all researchers in this field. There are two key activities for the next generation of video coding standard, one is based on high performance, another one based on IP consideration. In this talk, the state of art of technologies for two directions will be reviewed, and future steps will be discussed.Biography: Wen Gao received his Ph.D. degree in electronics engineering from the University of Tokyo in 1991. He joined with the Harbin Institute of Technology from 1991 to 1995, as professor, chairman of department of computer science. He joined with Institute of Computing Technology (ICT), Chinese Academy of Sciences (CAS), as professor from 1996 to 2005. During his career at CAS, he served as the managing director of ICT from 1998 to 1999, the vice president of Graduate School of Chinese Academy of Sciences from 2000 to 2004, the vice president of University of Science and Technology China from 2000 to 2003. He is joining with the Peking University as professor since 2006. Dr. Gao is working at the areas of image and video processing, in particular at video coding and video analysis. He is the leader of Chinese National Body for MPEG standard, as well as the funder of AVS standard. He is an IEEE fellow.Hosted by Professor C.-C.Jay Kuo
