Optimized projection-free algorithms for online learning: construction and worst-case analysis
Julien Weibel, Pierre Gaillard, Wouter M. Koolen +1
This work studies and develop projection-free algorithms for online learning with linear optimization oracles (a.k.a. Frank-Wolfe) for handling the constraint set. More precisely,…
