Multiplicative updates for symmetric-cone factorizations

Yong Sheng Soh, Antonios Varvitsiotis

Given a matrix $X \in R_{+}^{m \times n}$ with non-negative entries, the cone factorization problem over a cone $K \subseteq R^{k}$ concerns computing $\{ a_1,…

A Non-commutative Extension of Lee-Seung's Algorithm for Positive Semidefinite Factorizations

Yong Sheng Soh, Antonios Varvitsiotis

Given a matrix $X \in R_{+}^{m \times n}$ with nonnegative entries, a Positive Semidefinite (PSD) factorization of $X$ is a collection of $r \times r$ -dimensional PSD matrices…
