Detailed Description

Base layer for RBM models.

Member Function Documentation

const std::vector<Param*> singa::RBMLayer::GetParams ( ) const
inlineoverridevirtual

Layers that have paramters must override this function.

Parameters
flagused to get the calling phase, e.g., forward of training (kForward | kTrain)
Returns
parameters associated with this layer

Reimplemented from singa::Layer.

void singa::RBMLayer::Setup ( const LayerProto &  proto,
int  npartitions 
)
overridevirtual

Setup layer properties.

Setup the shapes for data and parameters, also setup some properties based on the layer configuration and connected layers.

Parameters
protolayer configuration.
npartitionsnum of total partitions of the original layer. This layer should be setup as one partition.

Reimplemented from singa::Layer.

Reimplemented in singa::RBMHidLayer, and singa::RBMVisLayer.
