Public Methods

Method	Description
ComputeError ( double inputs ) : double	Computes the reconstruction error for a given set of input values.
DeepBeliefNetworkLearning ( DeepBeliefNetwork network ) : System	Creates a new DeepBeliefNetworkLearning algorithm.
GetLayerAlgorithm ( int layerIndex ) : IUnsupervisedLearning	Gets the unsupervised learning algorithm allocated for the given layer.
GetLayerInput ( double input ) : double[][]	Gets the learning data needed to train the currently selected layer. The return of this function should then be passed to RunEpoch(double[][]) to actually run a learning epoch.
GetLayerInput ( double batches ) : double[][][]	Gets the learning data needed to train the currently selected layer. The return of this function should then be passed to RunEpoch(double[][]) to actually run a learning epoch.
Run ( double input ) : double	Runs a single learning iteration.
RunEpoch ( double input ) : double	Runs a single batch epoch of the learning algorithm.
