Accelerated Affine-Invariant Convergence Rates of the Frank-Wolfe Algorithm with Open-Loop Step-Sizes
Elias Wirth, Javier Pena, Sebastian Pokutta
Recent papers have shown that the Frank-Wolfe algorithm (FW) with open-loop step-sizes exhibits rates of convergence faster than the iconic rate. In particula…

Accelerated and Sparse Algorithms for Approximate Personalized PageRank and Beyond
David Martínez-Rubio, Elias Wirth, Sebastian Pokutta
It has recently been shown that ISTA, an unaccelerated optimization method, presents sparse updates for the -regularized personalized PageRank problem, leading to cheap ite…
