Binary Component Decomposition of Matrices

Speaker: Richard Kueng, Physics, Mathematics and Astronomy, Caltech
Location: Annenberg 213

We study the problem of decomposing a low-rank matrix into a factor with binary entries, either from {±1} or from {0,1}, and an unconstrained factor. This research answers fundamental questions about the existence and uniqueness of these decompositions. It also leads to tractable factorization algorithms that succeed under a mild deterministic condition.

This is joint work with Joel Tropp (Caltech)
