MPSCNNAddGradient(3) MetalPerformanceShaders.framework MPSCNNAddGradient(3)NAMEMPSCNNAddGradientSYNOPSIS#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.
