Fisher information for geometric distribution
WebThe Fisher–Rao information metric yields a measure of distance between any two dissimilar probability distributions on a statistical manifold. The notion of distance between elements of a statistical manifold can be regarded as the degree of distinguishability between any two different probability distribution functions. Webassociated with each model. A key ingredient in our proofs is a geometric characterization of Fisher information from quantized samples. Keywords: Fisher information, statistical estimation, communication constraints, learn-ing distributions 1. Introduction Estimating a distribution from samples is a fundamental unsupervised learning problem that
