Accelerated, Parallel and Proximal Coordinate Descent
Olivier Fercoq, Peter Richtárik
We propose a new stochastic coordinate descent method for minimizing the sum of convex functions each of which depends on a small number of coordinates only. Our method (APPROX) is…

Parallel coordinate descent for the Adaboost problem
Olivier Fercoq
We design a randomised parallel version of Adaboost based on previous studies on parallel coordinate descent. The algorithm uses the fact that the logarithm of the exponential loss…

Smooth minimization of nonsmooth functions with parallel coordinate descent methods
Olivier Fercoq, Peter Richtárik
We study the performance of a family of randomized parallel coordinate descent methods for minimizing the sum of a nonsmooth and separable convex functions. The problem class inclu…
