Frank-wolfe fw algorithm
WebThe Frank-Wolfe (FW) algorithm is also known as the projection-free or condition gradient algorithm [22]. The main advantages of this algorithm are to avoid the projection step and WebThe classical Frank-Wolfe method was proposed by Marguerite Frank and Philip Wolfe in 1956 [7]. The algorithm is used to solve the general con-strained convex optimization problems of the form min x2D f(x) where f(x) is convex and continuously di erentiable, and the domain D is a compact convex subset of any vector space. The Frank-Wolfe method ...

Previous linear-rate results are of the form \exp( - t / d), while this paper shows that the rate can be improved to \exp( - t / dim(F*)) under strict complementary condition [Wolfe 1970], where dim(F*) is the dimension of the ...
Webthrough the Frank-Wolfe (FW) algorithm, also known as the conditional gradient algorithm [12]. Indeed, as we discuss in Sec. III-B, FW assumes a very simple, elegant form under simplex constraints, and has important computational advan-tages [9, 10, 13]. Our main contribution is to identify and formalize a set of conditions under which solving ... WebAsynchronous algorithms. Asynchronous algorithms that allow delayed parameter updates have been proposed ear-lier for stochastic gradient descent (Niu et al.,2011) and parallel BCD (Liu et al.,2014). We propose the first asyn-chronous algorithm for Frank-Wolfe. Our asynchronous scheme not only permits delayed minibatch updates, but
