In this paper we describe a generalized classification method for HMM-based speech recognition systems, that uses free energy as a discriminant function rather than conventional probabilities. The discriminant function incorporates a single adjustable temperature parameter T. The computation of free energy can be motivated using an entropy regularization, where the entropy grows monotonically with the temperature. In the resulting generalized classification scheme, teh values of T = 0 and T = 1… CONTINUE READING
