Global Linear Convergence of Evolution Strategies on More Than Smooth Strongly Convex Functions
Youhei Akimoto, Anne Auger, Tobias Glasmachers +1
Evolution strategies (ESs) are zeroth-order stochastic black-box optimization heuristics invariant to monotonic transformations of the objective function. They evolve a multivariat…

Fast Eigen Decomposition for Low-Rank Matrix Approximation
Youhei Akimoto
In this paper we present an efficient algorithm to compute the eigen decomposition of a matrix that is a weighted sum of the self outer products of vectors such as a covariance mat…
