Title: MINIMUM ENTROPY ESTIMATION AS A NEAR MAXIMUM-LIKELIHOOD METHOD AND ITS APPLICATION IN SYSTEM IDENTIFICATION WITH NON-GAUSSIAN NOISE

Abstract: We derive the Minimum Entropy Estimation (MEE) method from Information Theory to show the similarity of this method to the Maximum Likelihood Method for the linear regression problem. The result is a nonparametric-based identification technique that can be applied in any case with iid noise that outperforms estimators in this case, including the popular LS method and a recently-developed (and limited) version of the MEE. Performance-wise, the MEE method is comparable to the Expectation-Maximization (EM) method. Its application to FIR system identification produces a very efficient implementation of this technique.
