Abstract:A new class of statistical algorithms is presented and examined. The method is called the D-EM algorithm. This novel algorithm contains the traditional EM algorithm as a special case of D = 1. The choice of the design parameter D affects the eigenvalues of Hessian matrices for likelihood maximization. This causes much faster convergence than the traditional EM algorithm. Convergence theorems are given for the basic D-EM algorithm and its practical variants. Numerical evaluation shows fast convergence at nearly… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
