NAME
MPSCNNInstanceNormalization SYNOPSIS
#import <MPSCNNInstanceNormalization.h> Inherits MPSCNNKernel. Instance Methods (nonnull instancetype) - initWithDevice:dataSource: (nonnull instancetype) - initWithDevice: (nullable instancetype) - initWithCoder:device: (void) - reloadDataSource: (void) - reloadGammaAndBetaWithCommandBuffer:gammaAndBetaState: (MPSCNNInstanceNormalizationGradientState *__nullable) - resultStateForSourceImage:sourceStates:destinationImage: Properties float epsilon id< MPSCNNInstanceNormalizationDataSource > dataSource Additional Inherited Members Detailed Description This depends on Metal.framework This kernel normalizes each image, on a per-channel basis, to have zero mean and unit variance: for each image: for each channel: y = (x - mean) * gamma / sqrt(variance + epsilon) + beta; Method Documentation - (nullable instancetype) initWithCoder: (NSCoder *__nonnull) aDecoder(nonnull id< MTLDevice >) device NSSecureCoding compatability While the standard NSSecureCoding/NSCoding method -initWithCoder: should work, since the file can't know which device your data is allocated on, we have to guess and may guess incorrectly. To avoid that problem, use initWithCoder:device instead. Parameters: aDecoder The NSCoder subclass with your serialized MPSKernel device The MTLDevice on which to make the MPSKernel Returns: A new MPSCNNInstanceNormalization object, or nil if failure. Reimplemented from MPSCNNKernel. - (nonnull instancetype) initWithDevice: (nonnull id< MTLDevice >) device Use initWithDevice:dataSource instead Reimplemented from MPSCNNKernel. - (nonnull instancetype) initWithDevice: (nonnull id< MTLDevice >) device(nonnull id< MPSCNNInstanceNormalizationDataSource >) dataSource Initialize a MPSCNNInstanceNormalization kernel on a device. Parameters: dataSource An object conforming to the MPSCNNInstanceNormalizationDataSource protocol which - (void) reloadDataSource: (__nonnull id< MPSCNNInstanceNormalizationDataSource >) dataSource Reload data using a data source. Parameters: dataSource The data source which will provide the gamma and beta terms to scale and bias the normalized result respectively. - (void) reloadGammaAndBetaWithCommandBuffer: (__nonnull id< MTLCommandBuffer >) commandBuffer(MPSCNNNormalizationGammaAndBetaState *__nonnull) gammaAndBetaState Reload data using new gamma and beta terms contained within an MPSCNNInstanceNormalizationGradientState object. Parameters: commandBuffer The command buffer on which to encode the reload. gammaAndBetaState The state containing the updated weights which are to be reloaded. - (MPSCNNInstanceNormalizationGradientState * __nullable) resultStateForSourceImage: (MPSImage *__nonnull) sourceImage(NSArray< MPSState * > *__nullable) sourceStates(MPSImage *__nonnull) destinationImage Return a MPSCNNInstanceNormalizationGradientState object for the provided source image, source states, and destination image. Reimplemented from MPSCNNKernel. Property Documentation - (id<MPSCNNInstanceNormalizationDataSource>) dataSource [read], [nonatomic], [retain] The data source that the object was initialized with - epsilon [read], [write], [nonatomic], [assign] The epsilon value used to bias the variance when normalizing.
