Variational Bayes learning (VB) is widely applied to clustering problems as the low computational cost algorithm of Bayes learning using the mean field approximation.
The VB algorithm is achieved by minimizing the variational free energy.
The online Variational Bayes learning (Online VB) has been proposed by using the discounted variational free energy, which is an extension of the variational free energy for the online algorithm.
In this paper, we investigate the performance of the online VB by using
the exponential mixture modeland show experimentally that relative entropy terms consisting of the discounted variational free energy enable us to detect the change of cluster structure. |
