摘要:
The nonnegative Boltzmann machine (NNBM) is a recurrent neural network model that can describe multimodal nonnegative data. Application of maximum likelihood estimation to this model gives a learning rule that is analogous to that of the binary Boltzmann machine. While the model itself is analytically intractable an efficient stochastic version of the learning rule can be obtained using reflective slice sampling, since the slice boundaries can be determined analytically from the model. We compare this with the use of advanced mean field theory to learn a generative model for face image data.
