Non-Convex Rank Minimization via an Empirical Bayesian Approach
David Wipf
In many applications that require matrix solutions of minimal rank, the underlying cost function is non-convex leading to an intractable, NP-hard optimization problem. Consequently…

Dual-Space Analysis of the Sparse Linear Model
David Wipf, Yi Wu
Sparse linear (or generalized linear) models combine a standard likelihood function with a sparse prior on the unknown coefficients. These priors can conveniently be expressed as a…
