MPSCNNSubtractGradient(3) MetalPerformanceShaders.framework MPSCNNSubtractGradient(3) NAME
MPSCNNSubtractGradient SYNOPSIS
#import <MPSCNNMath.h> Inherits MPSCNNArithmeticGradient. Instance Methods (nonnull instancetype) - initWithDevice: Additional Inherited Members Detailed Description This depends on Metal.framework. Specifies the subtraction 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 subtract gradient operation for the primary source image is a copy operation on the input gradient image (for x - y, d/dx(x - y) = 1). This copy operation can be optimized away by the graph interface. For the secondary source image, the result is a negation of the gradient image from the previous layer (for x - y, d/dy(x - y) = -1). 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 subtraction gradient operator. Parameters: device The device the filter will run on. Returns: A valid MPSCNNSubtractGradient object or nil, if failure. Reimplemented from MPSCNNArithmeticGradient.
