Specified by:

randomize in interface Randomizer

Parameters:

d - The input value, not used.

Returns:

The random number.

randomize

public void randomize(BasicNetwork network,
                      int fromLayer)

Randomize one level of a neural network.

Parameters:

network - The network to randomize

fromLayer - The from level to randomize.

randomize

public void randomize(MLMethod method)

Randomize the synapses and biases in the basic network based on an array, modify the array. Previous values may be used, or they may be discarded, depending on the randomizer.

Specified by:

randomize in interface Randomizer

Parameters:

method - A network to randomize.

randomize

public void randomize(double[] d)

Description copied from interface: Randomizer

Specified by:

randomize in interface Randomizer

Parameters:

d - An array to randomize.

randomize

public void randomize(double[][] d)

Description copied from interface: Randomizer

Randomize the 2d array based on an array, modify the array. Previous values may be used, or they may be discarded, depending on the randomizer.

Specified by:

randomize in interface Randomizer
