Method Detail

randomize

void randomize(MLMethod network)

Randomize the synapses and bias values 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.

Parameters:

network - A network to randomize.

randomize

double randomize(double d)

Starting with the specified number, randomize it to the degree specified by this randomizer. This could be a totally new random number, or it could be based on the specified number.

Parameters:

d - The number to randomize.

Returns:

A randomized number.

randomize

void randomize(double[] d)

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

Parameters:

d - An array to randomize.

randomize

void randomize(double[][] d)

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.

Parameters:

d - An array to randomize.

randomize

void randomize(Matrix m)

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

Parameters:

m - A matrix to randomize.

randomize

void randomize(double[] d,
               int begin,
               int size)

Randomize an array.

Parameters:

d - The array to randomize.

begin - The beginning element.

size - The size of the array.

setRandom

void setRandom(GenerateRandom theRandom)

Explicitly set the Random source

Parameters:

theRandom - Random number generator.

getRandom

GenerateRandom getRandom()

Returns:

Retrieve the Random generator.
