Event Description: Michael Wakin , Department of Electrical Engineering and Computer Science , ÃÛÌÇÖ±²¥ 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...

Joel Zylberberg, Department of Physiology and Biophysics, University of ÃÛÌÇÖ±²¥ 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...
