[jira] [Resolved] (SINGA-9) Add Support for Restricted Boltzman Machine (RBM) model

     [ https://issues.apache.org/jira/browse/SINGA-9?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

wangwei resolved SINGA-9.
-------------------------
    Resolution: Fixed

The next release should consider the PCD algorithm and the training for DBM.

> This ticket is to implement RBM in SINGA.
> To training RBM models, the Contrastive Divergence (CD) algorithm should be implemented. 
> We have implemented a BPWorker to run the Back-Propagation algorithm. To implement the CD algorithm, we follow the same way to create a CDWorker whose RunOneBatch function controls the logic of the CD algorithm, including positive phase, negative phase and computing gradient phase.
> RBM's layers are different to the layers for feed-forward neural networks, hence new layers for RBM models should be added.
