Class MPSCNNGroupNormalization

  • All Implemented Interfaces:
    NSCoding, NSCopying, NSSecureCoding, NSObject
    public class MPSCNNGroupNormalization
extends MPSCNNKernel
    MPSCNNGroupNormalization [@dependency] This depends on Metal.framework This kernel normalizes each image, on a per-group basis, to have zero mean and unit variance: for each image: for each channel: y = (x - mean) * gamma / sqrt(variance + epsilon) + beta; The mean and variance are computed per group of channels, as given by the dataSource.

        public MPSCNNGroupNormalization initWithCoderDevice​(NSCoder aDecoder,
                                                    java.lang.Object 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.
        Overrides:
        initWithCoderDevice in class MPSCNNKernel
        Parameters:
        aDecoder - The NSCoder subclass with your serialized MPSKernel
        device - The MTLDevice on which to make the MPSKernel
        Returns:
        A new MPSCNNGroupNormalization object, or nil if failure.

      • initWithDevice

        public MPSCNNGroupNormalization initWithDevice​(java.lang.Object device)
        Description copied from class: MPSCNNKernel
        Standard init with default properties per filter type
        Overrides:
        initWithDevice in class MPSCNNKernel
        Parameters:
        device - The device that the filter will be used on. May not be NULL.
        Returns:
        A pointer to the newly initialized object. This will fail, returning nil if the device is not supported. Devices must be MTLFeatureSet_iOS_GPUFamily2_v1 or later.

        Return a MPSCNNGroupNormalizationGradientState object for the provided source image, source states, and destination image.
        Overrides:
        resultStateForSourceImageSourceStatesDestinationImage in class MPSCNNKernel
        Parameters:
        sourceImage - The MPSImage consumed by the associated -encode call.
        sourceStates - The list of MPSStates consumed by the associated -encode call, for a batch size of 1.
        destinationImage - The destination image for the encode call
        Returns:
        The list of states produced by the -encode call for batch size of 1. When the batch size is not 1, this function will be called repeatedly unless -isResultStateReusedAcrossBatch returns YES. If -isResultStateReusedAcrossBatch returns YES, then it will be called once per batch and the MPSStateBatch array will contain MPSStateBatch.length references to the same object.
