MPSCNNAddGradient(3)					 MetalPerformanceShaders.framework				      MPSCNNAddGradient(3)

NAME

       MPSCNNAddGradient

SYNOPSIS

       #import <MPSCNNMath.h>

       Inherits MPSCNNArithmeticGradient.

   Instance Methods
       (nonnull instancetype) - initWithDevice:

   Additional Inherited Members
Detailed Description
       This depends on Metal.framework.  Specifies the addition gradient operator. This arithmetic gradient filter requires the following inputs:
       gradient image from the previous layer (going backwards) and either the primary or the secondary source image from the forward pass. You
       will need a separate filter for the primary and secondary source images.

       Without broadcasting, the arithmetic add gradient operation is a copy operation on the input gradient image. It is the same operation for
       both the primary and secondary source images (for x + y, d/dx(x + y) = 1, d/dy(x + y) = 1). This copy operation can be optimized away by
       the graph interface.

       Setting the broadcasting parameters results in a reduction operation (sum) across all of the applicable broadcasting dimensions (rows,
       columns, feature channels, or any combination thereof) to produce the destination image of the size that matches the primary/secondary
       input images used in the forward pass.

Method Documentation
   - (nonnull instancetype) initWithDevice: (nonnull id< MTLDevice >) device
       Initialize the addition gradient operator.

       Parameters:
	   device The device the filter will run on.

       Returns:
	   A valid MPSCNNAddGradient object or nil, if failure.

       Reimplemented from MPSCNNArithmeticGradient.

NAME

       MPSCNNMultiplyGradient

SYNOPSIS

       #import <MPSCNNMath.h>

       Inherits MPSCNNArithmeticGradient.

   Instance Methods
       (nonnull instancetype) - initWithDevice:

   Additional Inherited Members
Detailed Description
       This depends on Metal.framework.  Specifies the multiplication gradient operator. This arithmetic gradient filter requires the following
       inputs: gradient image from the previous layer (going backwards) and either the primary or the secondary source image from the forward
       pass. You will need a separate filter for the primary and secondary source images.

       Without broadcasting, the arithmetic multiply gradient operation is an element-wise multiplication operation between the gradient image
       from the previous layer (going backwards) and:

       o The secondary source image from the forward pass for the primary source filter (for x * y, d/dx(x * y) = y).

       o The primary source image from the forward pass for the secondary source filter (for x * y, d/dy(x * y) = x).

       Setting the broadcasting parameters results in a reduction operation (sum) across all of the applicable broadcasting dimensions (rows,
       columns, feature channels, or any combination thereof) to produce the destination image of the size that matches the primary/secondary
       input images used in the forward pass.

Method Documentation

       Parameters:
	   device The device the filter will run on.

       Returns:
	   A valid MPSCNNMultiplyGradient object or nil, if failure.
