 @Properties(inherit=caffe.class)
public class FloatMultinomialLogisticLossLayer
extends FloatLossLayer

\brief Computes the multinomial logistic loss for a one-of-many classification task, directly taking a predicted probability distribution as input. When predictions are not already a probability distribution, you should instead use the SoftmaxWithLossLayer, which maps predictions to a distribution using the SoftmaxLayer, before computing the multinomial logistic loss. The SoftmaxWithLossLayer should be preferred over separate SoftmaxLayer + MultinomialLogisticLossLayer as its gradient computation is more numerically stable.

Method Detail

Reshape

@Virtual
public void Reshape(@Const @ByRef
                             FloatBlobVector bottom,
                             @Const @ByRef
                             FloatBlobVector top)

Description copied from class: FloatLayer

\brief Adjust the shapes of top blobs and internal buffers to accommodate the shapes of the bottom blobs.

Overrides:

Reshape in class FloatLossLayer

Parameters:

bottom - the input blobs, with the requested input shapes

top - the top blobs, which should be reshaped as needed This method should reshape top blobs as needed according to the shapes of the bottom (input) blobs, as well as reshaping any internal buffers and making any other necessary adjustments so that the layer can accommodate the bottom blobs.
