16th Joint Symposium on Neural Computation

University of Southern California
Los Angeles, California



May 16, 2009



In 1994, the Institute for Neural Computation at UCSD hosted the first Joint Symposium on Neural Computation with Caltech. This Symposium brought together students and faculty for a day of short presentations. Since then, this Symposium has rotated between San Diego, Caltech, UCI, UCLA and USC.
