Neural Network-based minimum mean square (MMS), maximum a posteriori (MAP), and maximum likelihood (ML) parameter estimation are considered here. Ihe multilayer perceptron (MLP) is shown to approximate the minimum mean square estimator. Linear transfonns are used to compress data for the purpose of eficient parameter estimation. Raw and transform domain lower b o u h are developed and used as an optimality criteria in a procedure defined to compare various transfomations.
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.
