Method Details

normalize

public double[] normalize(double[] input)

Description copied from interface: VectorNormalizer

Normalizes the input array in some fashion specified by the class.

Specified by:

normalize in interface VectorNormalizer

Parameters:

input - The input to normalize.

Returns:

The normalized array.

normalizeInPlace

public void normalizeInPlace(double[] input)

Description copied from interface: VectorNormalizer

In place normalization of the array.

Note: This default implementation performs a copy by calling the standard normalize method.

Specified by:

normalizeInPlace in interface VectorNormalizer

Parameters:

input - The input to normalize.

exportNormalizer

public ONNXNode exportNormalizer(ONNXNode input)

Returns the ONNX softmax node over the 2nd dimension.

Specified by:

exportNormalizer in interface VectorNormalizer

Parameters:

input - The node to be normalized according to this implementation.

Returns:

ONNX softmax node of input.
