Method Detail

updateBias

public abstract void updateBias(int i,
                                double aDelta)

Updates a bias with the calculated delta value.

Parameters:

i - the index of the bias to update.

aDelta - the calculated delta value.

updateWeight

public abstract void updateWeight(int j,
                                  int k,
                                  double aDelta)

Updates a weight with the calculated delta value.

Parameters:

j - the input index of the weight to update.

k - the output index of the weight to update.

aDelta - the calculated delta value.

storeWeightsBiases

public abstract boolean storeWeightsBiases()

Checks if the weights or biases will be stored this cycle.

Returns:

true if the weights or biases will be stored this cycle, false otherwise.
