| Abstract(in English) | We formerly proposed an on-line EM algorithm for the normalized Gaussian network model. Athough the algorithm conducts on-line model selection schemes based on probabilistic interpretation, ambiguity has remained in their criterion. This study intends to remove the ambiguity by using a Bayes learning method. We propose an on-line variational Bayes learning method, in which the Bayes learning for the NGnet is implemented as a similar algorithm to the on-line EM algorithm. When applied to a simple two-dimensional function approximation problem and eight-dimensional benchmark problems, our method exhibits good performance. |
