On Distributed Averaging for Stochastic k-PCA
NeurIPS 2019poster
In the stochastic k-PCA problem, we are given i.i.d. samples from an unknown distribution over vectors, and the goal is to compute the top k eigenvalues and eigenvectors of the moment matrix. In the simplest distributed variant, we have 'm' machines each of which receives 'n' samples. Each machine p…
