Detailed Description

A MPSNNSlice filter that operates as the conjugate computation for concatentation operators during training As concatenation is formally just a copy and not a computation, there isn't a lot of arithmetic for the slice operator to do, but we still need to extract out the relevant portion of the gradient of the input signal that went into the corresponding concatenation destination image.

  - (nonnull instancetype) initWithSourceGradient: (MPSNNImageNode *__nonnull) gradientSourceNode(MPSNNImageNode *__nonnull) sourceImage(MPSNNGradientStateNode *__nonnull) gradientState
Init a MPSNNConcatenationGradientNode Generally you should use [MPSNNConcatenationNode gradientFiltersWithSources:] instead.

Parameters:
    gradientSourceNode The gradient image functioning as input for the operator
    sourceImage The particular input image to the concatentation, if any, that the slice corresponds with
    gradientState The gradient state produced by the concatenation filter, consumed by this filter

  + (nonnull instancetype) nodeWithSourceGradient: (MPSNNImageNode *__nonnull) gradientSourceNode(MPSNNImageNode *__nonnull) sourceImage(MPSNNGradientStateNode *__nonnull) gradientState

Parameters:
    gradientSourceNode The gradient image functioning as input for the operator
