Method Documentation

  - (nonnull instancetype) initWithSourceGradient: (MPSNNImageNode *__nonnull) sourceGradient(MPSNNImageNode *__nonnull) sourceImage(MPSNNGradientStateNode *__nonnull) gradientState(double) scaleFactorX(double) scaleFactorY
A node to represent the gradient calculation for nearest upsampling training. [forwardFilter gradientFilterWithSources:] is a more convient way to do this.

Parameters:
    sourceGradient The input gradient from the 'downstream' gradient filter.
    sourceImage The input image from the forward filter node
    gradientState The gradient state from the forward filter
    scaleFactorX The X scale factor from the forward pass
    scaleFactorY The Y scale factor from the forward pass

Returns:
    A MPSCNNUpsamplingNearestGradientNode

  + (nonnull instancetype) nodeWithSourceGradient: (MPSNNImageNode *__nonnull) sourceGradient(MPSNNImageNode *__nonnull) sourceImage(MPSNNGradientStateNode *__nonnull) gradientState(double) scaleFactorX(double) scaleFactorY
A node to represent the gradient calculation for nearest upsampling training. [forwardFilter gradientFilterWithSources:] is a more convient way to do this.

Parameters:
    sourceGradient The input gradient from the 'downstream' gradient filter.
    sourceImage The input image from the forward filter node
    gradientState The gradient state from the forward filter
    scaleFactorX The X scale factor from the forward pass
    scaleFactorY The Y scale factor from the forward pass

Returns:
