Matrix Completion under Interval Uncertainty
Jakub Marecek, Peter Richtarik, Martin Takac
Matrix completion under interval uncertainty can be cast as matrix completion with element-wise box constraints. We present an efficient alternating-direction parallel coordinate-d…
Distributed Block Coordinate Descent for Minimizing Partially Separable Functions
Jakub Marecek, Peter Richtarik, Martin Takac
In this work we propose a distributed randomized block coordinate descent method for minimizing a convex function with a huge number of variables/coordinates. We analyze its comple…
Fast Distributed Coordinate Descent for Non-Strongly Convex Losses
Olivier Fercoq, Zheng Qu, Peter Richtárik +1
We propose an efficient distributed randomized coordinate descent method for minimizing regularized non-strongly convex loss functions. The method attains the optimal co…
