New KL Projection Method Enhances Doubly Stochastic Clustering

Researchers have developed a novel method for doubly stochastic clustering by employing exact Kullback--Leibler (KL) projection for low-rank factorizations. This approach utilizes non-negative factors with prescribed row marginals and a shared, learned column marginal, reducing the effective variables and enabling efficient matrix-free Hessian-vector products. The method is applied to doubly stochastic graph learning, allowing for the induction of an exactly doubly stochastic graph without materializing a large optimization variable. Experiments in matched clustering demonstrate competitive accuracy and favorable anytime behavior. AI
