MPSCNNInstanceNormalizationGradientState SYNOPSIS
#import <MPSCNNInstanceNormalization.h> Inherits MPSNNGradientState. Instance Methods (nonnull instancetype) - initWithDevice:textureDescriptor: (nonnull instancetype) - initWithResource: (nonnull instancetype) - initWithDevice:bufferSize: Class Methods (nonnull instancetype) + temporaryStateWithCommandBuffer:textureDescriptor: (nonnull instancetype) + temporaryStateWithCommandBuffer: (nonnull instancetype) + temporaryStateWithCommandBuffer:bufferSize: Properties MPSCNNInstanceNormalization * instanceNormalization MPSCNNNormalizationGammaAndBetaState * gammaAndBetaState __nonnull id< MTLBuffer > gradientForGamma __nonnull id< MTLBuffer > gradientForBeta Detailed Description This depends on Metal.framework A state to hold information necessary to execute a gradient pass for MPSCNNInstanceNormalization. Gradient states should be created by using the forward kernel's methods. This will ensure that the state captures all information necessary to execute the corresponding gradient pass.

MPSCNNBatchNormalizationState SYNOPSIS
#import <MPSCNNBatchNormalization.h> Inherits MPSState. Instance Methods (nonnull instancetype) - initWithResource: (void) - reset (nullable id< MTLBuffer >) - mean (nullable id< MTLBuffer >) - variance (nullable id< MTLBuffer >) - gradientForGamma (nullable id< MTLBuffer >) - gradientForBeta Class Methods (nonnull instancetype) + temporaryStateWithCommandBuffer:bufferSize: (__nonnull instancetype) + temporaryStateWithCommandBuffer:textureDescriptor: Properties MPSCNNBatchNormalization * batchNormalization MPSCNNNormalizationGammaAndBetaState * gammaAndBetaState Detailed Description MPSCNNBatchNormalizationState encapsulates the data necessary to execute batch normalization. MPSCNNBatchNormalizationState cannot initialize the size of its own underlying resources. Use [MPSCNNBatchNormalizationStatistics resultStateForSourceImages:] or [MPSCNNBatchNormalizationStatistics temporaryResultStateForCommandBuffer:sourceImages:]. Method Documentation - (nullable id<MTLBuffer>) gradientForBeta Return an MTLBuffer object containing the values of the gradient of the loss function with respect to the bias terms. If a MPSCNNBatchNormalizationGradient kernel has not successfully generated these values nil will be returned. - (nullable id<MTLBuffer>) gradientForGamma Return an MTLBuffer object containing the values of the gradient of the loss function with respect to the scale factors. If a MPSCNNBatchNormalizationGradient kernel has not successfully generated these values nil will be returned. - (nonnull instancetype) initWithResource: (__nullable id< MTLResource >) resource Unavailable. Use MPSCNNBatchNormalizationStatistics methods to initialize the state object. Reimplemented from MPSState. - (nullable id<MTLBuffer>) mean Return an MTLBuffer object with the most recently computed batch mean values. - (void) reset Reset any accumulated state data to its initial values. + (nonnull instancetype) temporaryStateWithCommandBuffer: (__nonnull id< MTLCommandBuffer >) cmdBuf(size_t) bufferSize Unavailable. Use MPSCNNBatchNormalizationStatistics methods to create the temporary state object. Reimplemented from MPSState. + (__nonnull instancetype) temporaryStateWithCommandBuffer: (__nonnull id< MTLCommandBuffer >) cmdBuf(MTLTextureDescriptor *__nonnull) descriptor Create a MPSState holding a temporary MTLTexture Parameters: cmdBuf The command buffer against which the temporary resource is allocated descriptor A descriptor for the new temporary texture Reimplemented from MPSState. - (nullable id<MTLBuffer>) variance Return an MTLBuffer object with the most recently computed batch variance values.
