Title: Recent perspectives on Frank-Wolfe methods in Machine Learning
Abstract
The Frank-Wolfe algorithm is a classical iterative scheme for convex minimization which has recently been the subject of a renewed interest from researchers. Its solid theoretical properties and sparsity guarantees make it a suitable choice for a wide range of problems arising in Machine Learning, statistics, bioinformatics and other fields. In this seminar, we provide a self-contained introduction to Frank-Wolfe methods and their applications to Machine Learning. We also discuss some variants of the original method and other techniques which can improve on the performance of the standard Frank-Wolfe iteration from both a theoretical and a practical point of view. We motivate our discussion by presenting experimental results on several medium and large-scale SVM datasets.
