    • Method Detail

      • beta

        org.moe.natj.general.ptr.FloatPtr beta()
        Return a pointer to an array containing the beta terms. Must have numberOfFeatureChannels values since scaling is done per feature channel.

      • copyWithZoneDevice

        default java.lang.Object copyWithZoneDevice​(org.moe.natj.general.ptr.VoidPtr zone,
                                            MTLDevice device)
        Optional copy method to create a copy of the data source for use with a new device.
        Parameters:
        zone - The NSZone on which to allocate.
        device - The device where the kernel which uses this data source will be used.
        Returns:
        A pointer to a copy of this data source.

      • encodeWithCoder

        default void encodeWithCoder​(NSCoder aCoder)
        Optional NSSecureCoding compatibility.

      • epsilon

        default float epsilon()
        An optional tiny number to use to maintain numerical stability. output_image = (input_image - mean[c]) * gamma[c] / sqrt(variance[c] + epsilon) + beta[c]; Defalt value if method unavailable: FLT_MIN

      • gamma

        org.moe.natj.general.ptr.FloatPtr gamma()
        Return a pointer to an array containing the gamma terms. Must have numberOfFeatureChannels values since scaling is done per feature channel.

      • initWithCoder

        default java.lang.Object initWithCoder​(NSCoder aDecoder)
        NS_DESIGNATED_INITIALIZER

      • label

        java.lang.String label()
        A label that is transferred to the group normalization filter at init time Overridden by a MPSCNNGroupNormalizationNode.label if it is non-nil.

      • numberOfFeatureChannels

        long numberOfFeatureChannels()
        [@property] The number of feature channels that are normalized.

      • numberOfGroups

        long numberOfGroups()
        [@property] The number of groups used. numberOfFeatureChannels/numberOfGroups channels are normalized together.

      • setNumberOfGroups

        void setNumberOfGroups​(long value)
        [@property] The number of groups used. numberOfFeatureChannels/numberOfGroups channels are normalized together.

      • _supportsSecureCoding

        default boolean _supportsSecureCoding()
