Research Abstract

Likelihood optimization for learning algorithms was generalized by using the alpha-logarithm. This generalization led to a faster convergence than traditional methods. Algorithms on hidden Markov model estimation and independent component analysis were chosen since they have high ramifications. The use of the alpha-logarithm appears as the utilization of past information via momentum terms. This property enabled faster convergence than traditional methods.
