A Bregman firmly nonexpansive proximal operator for baryconvex optimization

Mastane Achab

We present a generalization of the proximal operator defined through a convex combination of convex objectives, where the coefficients are updated in a minimax fashion. We prove th…

Beyond Log-Concavity: Theory and Algorithm for Sum-Log-Concave Optimization

Mastane Achab

This paper extends the classic theory of convex optimization to the minimization of functions that are equal to the negated logarithm of what we term as a sum-log-concave function,…
