Method Detail

getWeight

java.lang.Double getWeight(int parentLayerId,
                         int parentNeuronId,
                         int childNeuronId)
                           throws GSException

Gets value of specified weight.

Parameters:

parentLayerId - id of layer with outgoing neuron from range [1, number of layers]

parentNeuronId - id of outgoing neuron from range [0, number of neurons in outgoing layer - 1]

childNeuronId - id of incomming neuron from range [0, number of neurons in incomming layer - 1]

Returns:

required weight or null if such connection doesn't exists

Throws:

GSException

getActivationFunction

NeuronActivationFunctionType getActivationFunction(int layerId)
                                                   throws GSException

Gets type of activation function in specified layer.

Parameters:

layerId - layer id from range [1, number of layers]

Returns:

activation function type or null if such function is not specified for that layer

Throws:

getThreshold

java.lang.Double getThreshold(int layerId,
                            int neuronId)
                              throws GSException

Gets threshold value for specified neuron.

Parameters:

layerId - layer id from range [1, number of layers]

neuronId - neuron id from range [0, number of neurons in layer - 1]

Returns:

required value of threshold or null if threshold is not specified

Throws:

GSException
