Inheritance: BasicTraining, ILearningRate

Méthodes publiques

Méthode	Description
AutoDecay ( ) : void	Should be called each iteration if autodecay is desired.
BasicTrainSOM ( SOMNetwork network, double learningRate, IMLDataSet training, INeighborhoodFunction neighborhood ) : System	Create an instance of competitive training.
Decay ( double d ) : void	Called to decay the learning rate and radius by the specified amount.
Decay ( double decayRate, double decayRadius ) : void	Decay the learning rate and radius by the specified amount.
Iteration ( ) : void	Perform one training iteration.
Pause ( ) : TrainingContinuation
Resume ( TrainingContinuation state ) : void
SetAutoDecay ( int plannedIterations, double startRate, double endRate, double startRadius, double endRadius ) : void	Setup autodecay. This will decrease the radius and learning rate from the start values to the end values.
SetParams ( double rate, double radius ) : void	Set the learning rate and radius.
ToString ( ) : String
TrainPattern ( IMLData pattern ) : void	Train the specified pattern. Find a winning neuron and adjust all neurons according to the neighborhood function.

Méthode	Description
ApplyCorrection ( ) : void	Loop over the synapses to be trained and apply any corrections that were determined by this training iteration.
CopyInputPattern ( Matrix matrix, int outputNeuron, IMLData input ) : void	Copy the specified input pattern to the weight matrix. This causes an output neuron to learn this pattern "exactly". This is useful when a winner is to be forced.
DetermineNewWeight ( double weight, double input, int currentNeuron, int bmu ) : double	Determine the weight adjustment for a single neuron during a training iteration.
ForceWinners ( Matrix matrix, int won, IMLData leastRepresented ) : bool	Force any neurons that did not win to off-load patterns from overworked neurons.
Train ( int bmu, Matrix matrix, IMLData input ) : void	Train for the specified synapse and BMU.
TrainPattern ( Matrix matrix, IMLData input, int current, int bmu ) : void	Train for the specified pattern.

Should be called each iteration if autodecay is desired.
