NAME

MPSMatrixLogSoftMaxGradient

SYNOPSIS

#import <MPSMatrixSoftMax.h>

Inherits MPSMatrixSoftMaxGradient.

Detailed Description

This depends on Metal.framework.

Computes the gradient corresponding to a forward MPSMatrixLogSoftMax object.

A MPSMatrixLogSoftMaxGradient object computes:

            dL_dX_ij = dL_dY_ij - exp(Y_ij * sum_k(dL_dY_ik))


        Where dL_dX is the resulting gradient of the loss function with respect to


        the original input to the forward MPSMatrixLogSoftMax operation, Y is


        the output of the forward MPSMatrixLogSoftMax operation, and dL_dY is the


        gradient of the loss function with respect to Y.
