| Abstract(in English) | The Wake-Sleep algorithm is a stochastic learning algorithm which enables Helmholtz machine, asymmetrically connected layered network to work in practice. Experimentally, several positive results have been reported so far, but theoritically, little is known about its properties even for a simple model.In this paper, we analyse the dynamics of the Wake-Sleep Algorithm applying to a single factor analys is problem in respect with statitical mechanics context. As a result, we clarify the convergence properties of WS algorithm, even for the case of using finite learning rate. |
