WebAbstract—Consider the Fisher information for estimating a vector 2Rd from the quantized version of a statistical sample X ˘f(xj ). Let M be a k-bit quantization of X. We provide a geometric characterization of the trace of the Fisher information matrix I M( ) in terms of the score function S (X). When k= 1, we exactly solve the extremal ... WebInformation geometric optimization (IGO) is a general framework for stochastic optimization problems aiming at limiting the influence of arbitrary parametrization choices: the initial problem is transformed into the optimization of a smooth function on a Riemannian manifold, defining a parametrization-invariant first order differential equation and, thus, …
