NAME

       MPSNNGradientStateNode

SYNOPSIS

       #import <MPSNNGraphNodes.h>

       Inherits MPSNNStateNode.

       Inherited by MPSCNNConvolutionGradientStateNode.

   Additional Inherited Members
Detailed Description
       During training, each MPSNNFilterNode has a corresponding MPSNNGradientFilterNode for the gradient computation for trainable parameter
       update. The two communicate through a MPSNNGradientStateNode or subclass which carries information about the inference pass settings to the
       gradient pass. You can avoid managing these -- there will be many! -- by using -[MPSNNFilterNode gradientFilterWithSources:] to make the
       MPSNNGradientFilterNodes. That method will append the necessary extra information like MPSNNGradientState nodes and inference filter source
       image nodes to the object as needed.
