A better convergence analysis of the block coordinate descent method for large scale machine learning

Ziqiang Shi, Rujie Liu

This paper considers the problems of unconstrained minimization of large scale smooth convex functions having block-coordinate-wise Lipschitz continuous gradients. The block coordi…

Empirical study of PROXTONE and PROXTONE $^{+}$ for Fast Learning of Large Scale Sparse Models

Ziqiang Shi, Rujie Liu

PROXTONE is a novel and fast method for optimization of large scale non-smooth convex problem \cite{shi2015large}. In this work, we try to use PROXTONE method in solving large scal…
