Department Colloquium - Michael Wakin

Feb. 5, 2016

Event Description: Michael Wakin , Department of Electrical Engineering and Computer Science , Colorado School of Mines Slepian Sequences and Subspace Models for Signal Processing Low-dimensional subspace models offer a convenient representation for many high-dimensional signals; such models form the backbone of least-squares signal processing and many common compression techniques...

Department Colloquium - Joel Zylberberg

Jan. 22, 2016

Joel Zylberberg, Department of Physiology and Biophysics, University of Colorado School of Medicine Mathematical and Computational Principles Underlying Robust Perception and Memory The nervous system is a surprisingly noisy place. For example, if one presents the exact same stimulus to an animal many times, and records the activities of their...
