Frank wolfe algorithm example
Webexamples and Frank-Wolfe algorithm. We present our pro-posed Frank-Wolfe framework in Section 3, and the main theory in Section 4. In Section 5, we compare the pro-posed algorithms with state-of-the-art adversarial attack al-gorithms on ImageNet and MNIST datasets. Finally, we conclude this paper in Section 6. 2 Related Work WebIn these situations, the Frank-Wolfe algorithm (FW) (Frank & Wolfe,1956), a.k.a. conditional gradient algorithm (Lev-itin & Polyak,1966), becomes the method of choice, as it is a simple projection-free algorithm relying on a lin-ear minimization oracle over C. At each iteration, it calls the oracle v t argmin v2C hrf(x t);viand moves in

http://researchers.lille.inria.fr/abellet/talks/frank_wolfe.pdf WebA colleague was explaining to me that the Frank-Wolfe algorithm is a descent algorithm (i.e. its objective value decreases monotonically at each iteration). However, when I tried simulating it, my curve is not monotonically decrease, but does converge. It's possible I'm just a bad coder, but can someone point me to a proof somewhere that shows ...
