Expectation Maximization and Mixture Modeling Tutorial

Abstract

This technical report describes the statistical method of expectation maximization (EM) for parameter estimation. Several of 1D, 2D, 3D and n-D examples are presented in this document. Applications of the EM method are also demonstrated in the case of mixture modeling using interactive Java applets in 1D (e.g., curve fitting), 2D (e.g., point clustering and classification) and 3D (e.g., brain tissue classification).
