Abstract

In this letter we present an on-line learning version of the Fokker-Planck machine. The method makes use of a regularizedconstrained normalized LMS algorithm in order to estimatethe time-derivative of the parameter vector of a radial basis functionnetwork. The RBF network parametrizes a transition densitywhich satisfies a Fokker-Planck equation, associated to continuoussimulated annealing. On-line learning using the constrained normalized LMSmethod is necessary in order to make the Fokker-Planck machine applicable to large scale nonlinear optimization problems.
