Efficient Solution of Large Overdetermined Systems of Equations by a Monte Carlo Method
Tue, Jan 18, 2011 @ 11:00 AM - 12:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Yunsong Huang , Ph.D. student
Talk Title: Efficient Solution of Large Overdetermined Systems of Equations by a Monte Carlo Method
Abstract: Large overdetermined system of linear equations, expressed as A x = b, arises from applications such as seismic imaging. The rows of the matrix A can be randomly encoded and lumped up, resulting in a matrix with much fewer number of rows, thereby allowing a more efficient solution. This manipulation step can be embedded in least-squares iterative solution of the original system of equations. At each iteration, an independently encoded and lumped matrix is in effect, guiding the update of x, in the least-squares sense. Overall, this approach results in significant savings in computational cost. Experiments in seismic imaging validate the merits of the proposed method.
Biography: Yunsong Huang received a B.S. degree in physics from the University of Science and Technology of China, and a master's degree in Electrical Engineering from the University of Southern California. He is currently a Ph.D. student in the Earth Science and Engineering Program at King Abdullah University of Science and Technology (KAUST). His research interests include seismic imaging and signal processing.

Talk Title: MHI Ph.D. Scholar Finalist Presentation
Abstract: You are all invited to an exciting event being held for the first time in our department: talks by nine stellar Ph.D. students competing to become 2011 Ming Hsieh Institute Ph.D. Scholars. The Ph.D. Scholar Program is a venture of the newly-founded Ming Hsieh Institute, that aims to support senior Ph.D. students interested in pursuing an academic career. These finalists have been selected from nominations submitted by faculty. At the event each finalist will present a 12-minute talk about their research. It is anticipated that five MHI Scholars will be selected from this pool, based on an evaluation of their talks by a faculty panel.
All Electrical Engineering students and faculty are invited. Light refreshments will be served.
