MPSCNNMultiplyGradient(3) MetalPerformanceShaders.framework MPSCNNMultiplyGradient(3)NAMEMPSCNNMultiplyGradientSYNOPSIS#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 - (nonnull instancetype) initWithDevice: (nonnull id< MTLDevice >) device Initialize the multiplication gradient operator. Parameters: device The device the filter will run on. Returns: A valid MPSCNNMultiplyGradient object or nil, if failure. Reimplemented from MPSCNNArithmeticGradient.
