Discovering Convolutive Speech Phones Using Sparseness and Non-negativity
Discovering a representation that allows auditory data to be parsimoniously represented is useful for many machine learning and signal processing tasks. Such a representation can b...

On the Effectiveness of Looking Ahead in Search for Answer Sets
Abstract. Most complete answer set solvers are based on DPLL. One of the constraint propagation methods is the so-called lookahead, which has been somewhat controversial, due to it...

Reverse-Convex Programming for Sparse Image Codes
Abstract. Reverse-convex programming (RCP) concerns global optimization of a specific class of non-convex optimization problems. We show that a recently proposed model for sparse ...
