Constructor Detail

NormalizeInput

public NormalizeInput(NeuralData input,
                      NormalizeInput.NormalizationType type)

Normalize an input array into a matrix. The resulting matrix will have one extra column that will be occupied by the synthetic input.

Parameters:

input - The input array to be normalized.

type - What type of normalization to use.

Method Detail

calculateFactors

protected void calculateFactors(NeuralData input)

Determine both the normalization factor and the synthetic input for the given input.

Parameters:

input - The input to normalize.

createInputMatrix

protected Matrix createInputMatrix(NeuralData pattern,
                                   double extra)

Create an input matrix that has enough space to hold the extra synthetic input.

Parameters:

pattern - The input pattern to create.

extra - The synthetic input.

Returns:

A matrix that contains the input pattern and the synthetic input.

getInputMatrix

public Matrix getInputMatrix()

Get the resulting input matrix.

Returns:

The resulting input matrix.

getNormfac

public double getNormfac()

The normalization factor.

Returns:

The normalization factor.

getSynth

public double getSynth()

The synthetic input.

Returns:

The synthetic input.
