Bio: Matus Telgarsky obtained his PhD in Computer Science from UCSD in 2013 under Sanjoy Dasgupta; while there, his research focused primarily upon optimization and statistical aspects of unconstrained and unregularized algorithms (e.g., boosting), and to a lesser extent, clustering. He then served as a postdoctoral researcher at Rutgers University and the University of Michigan, as well as a consulting researcher at Microsoft Research in New York City. Since fall 2016, he has been an assistant professor at the University of Illinois, Urbana-Champaign; his most recent interests are representation and nonconvex optimization.

We are glad to have Prof. Seth Hutchinson, as our guest speaker for this week’s social hour on Friday, Nov 10 at 3:00PM in 369 CSL. In this session Prof. Hutchinson will talk about “What’s next for Robotics?”.

We are very pleased to have Ryan Corey as our guest speaker for this week’s social hour on Friday, Nov 3 at 3:00PM in 369 CSL. In this week’s social hour Ryan will talk about “Multichannel Signal Processing for Augmented Listening Devices”.

Abstract: Augmented listening devices, such as hearing aids, personal sound amplifiers, and an emerging category of “smart” headphones, promise to enhance human listening by processing the sound we hear to reduce noise and improve understanding, but most products available today perform poorly in very noisy environments. In our research, we show how advanced listening devices can use microphone arrays to separate, process, and enhance multiple sound sources even in challenging listening environments.

Bio: Ryan Corey is a PhD student working with Professor Andrew Singer in CSL. A Chicago-area native, Ryan completed his Bachelor’s degree in Electrical Engineering at Princeton University, then returned to Illinois for graduate school. In 2014, he was awarded the National Science Foundation Graduate Research Fellowship. Ryan studies speech and audio signal processing with a particular focus on multichannel processing for hearing aid applications. When he’s not playing with microphones, Ryan enjoys travel, cooking, and silly hats.

We are glad to have Xiang-Shen Ye, as our speaker for this week’s social hour on Friday, October 27 at 3:00PM in 369 CSL. This session is titled as “Optimization in Curbing Risk Contagion among Financial Institutes”.

Abstract: Financial institutions are interconnected by holding debt claims against each other. It can be shown that a good mechanism of default liquidation may improve the total wealth of the financial system. this problem can be formulated as a nonlinear optimization problem with constraints and propose an optimal liquidation policy to minimize the system’s loss. It can be shown that this problem resembles a Markov decision problem (MDP) and therefore we can apply the direct-comparison based optimization approach to solve this problem.

Bio: Xiang-Shen is a visiting Ph.D. student at Coordinated Science Laboratory working under the supervision of Professor Tamer Başar. Currently he is pursuing the Ph.D. degree in the Department of Automation, Shanghai Jiao Tong University, Shanghai, China, under the supervision of Professor Xi-Ren Cao. He received the B.Eng. degree in automation science from Beijing University of Aeronautic and Astronautics, Beijing, China, in 2013. His current research interests include discrete event dynamic systems, stochastic learning and optimization, and financial engineering. In his free time, he enjoys reading, hiking, skiing, and playing basketball.

We are glad to have Suryanarayana Sankagiri as our guest speaker for this week’s social hour on Friday, Sept 8 at 3:00PM in 369 CSL. Surya will talk about “Community Detection: A Fresh Perspective“.
Abstract: Community detection is the problem of finding dense subgraphs within a large graph. It arises in the analysis of many different types of networks, be it social networks or citation networks. My research involves the development of a new model for generating graphs with communities, and finding algorithms that work well for this model. The exciting part about this research is that it essentially involves concepts learned in courses like ECE 534

Bio: Surya is a 2nd year graduate student in the ECE department, working with Prof. Bruce Hajek. He is currently working on community detection, a form of unsupervised learning. Apart from communications theory (currently being pursued as theoretical machine learning), he is also interested control theory. He did his undergrad in IIT Bombay, India. In his free time, he enjoys cooking, playing badminton and tennis, and cycling around Champaign.
