Semidefinite Programming for Gradient and Hessian Computation in Maximum Entropy Estimation

Jean B. Lasserre(lasserre***at***laas.fr)

Abstract: We consider the classical problem of estimating a density on $[0,1]$ via some maximum entropy criterion. For solving this convex optimization problem with algorithms using first-order or second-order methods, at each iteration one has to compute (or at least approximate) moments of some measure with a density on $[0,1]$, to obtain gradient and Hessian data. We propose a numerical scheme based on semidefinite programming that avoids computing quadrature formula for this gradient and Hessian computation.
