A Phase Space Approach to Minimax Entropy Learning and the Minutemax Approximations
There has been much recent work on measuring image statistics and on learning probability distributions on images. We observe that the mapping from images to statistics is many-to...

Algorithms for Dynamic Spectrum Access with Learning for Cognitive Radio
We study the problem of dynamic spectrum sensing and access in cognitive radio systems as a partially observed Markov decision process (POMDP). A group of cognitive users cooperati...

Spectral Multiscale Coverage: A uniform coverage algorithm for mobile sensor networks
Abstract— In this paper we propose centralized feedback control laws for mobile sensor networks so that sensor trajectories cover a given domain as uniformly as possible. The des...
