Exact finite approximations of average-cost countable Markov decision processes
For a countable-state Markov decision process we introduce an embedding which produces a finite-state Markov decision process. The finite-state embedded process has the same optim...

Gibbs Construction in Steganography
Abstract--We make a connection between steganography design by minimizing embedding distortion and statistical physics. The unique aspect of this work and one that distinguishes it...

Unsupervised Learning of Categories from Sets of Partially Matching Image Features
We present a method to automatically learn object categories from unlabeled images. Each image is represented by an unordered set of local features, and all sets are embedded into...

Efficient fine granular scalable video coding
In this work we present an efficient fine granular scalable video compression scheme which supports a fast bit rate adaptation independent of the encoder. The proposed scheme gene...
