Random Matrices: Geometry, Random Matrices and Statistical Inference - January 16-19, 2007
Workshop Information
Geometry, Random matrices, and Statistical Inference was a workshop within the SAMSI program on High Dimensional Inference and Random Matrices. It was held January 16-19, 2007 at the NISS Building in Research Triangle Park, NC.
The four day workshop began the semester long focus on Geometry and Random Matrices. Both algorithms and the fundamental mathematical objects computed by the algorithms were stressed. This workshop was followed by a semester long working group on "Geometry, Random Matrices, and Statistical Inference."
The format of the workshop was two talks in the morning and one in the afternoon. All talks were one hour and there was considerable time for discussions.
The list of confirmed participants included: Sanjoy Dasgupta (University of California, San Diego), Vladimir Koltchinskii (Georgia Institute of Technology), Yoon Lee (Ohio State University), Guy Lebanon (Purdue University), Liza Levina (University of Michigan), Mauro Maggioni (Duke University), Yuriy Mileyko (Duke University), Partha Niyogi (University of Chicago), Tao Shi (Ohio State University), Jonathan Taylor (Stanford University)
Workshop Committee: Misha Belkin (The Ohio State University, Chair), Feng Liang (University of Illinois at Urbana-Champaign), Sayan Mukherjee (Local Scientific Coordinator), James Damon (SAMSI, Directorate Liaison).
