Method Detail

beta

@Nullable
@Nullable 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

@NotNull
default @NotNull MPSCNNGroupNormalizationDataSource copyWithZoneDevice(@Nullable
                                                                       @Nullable org.moe.natj.general.ptr.VoidPtr zone,
                                                                       @Nullable
                                                                       @Nullable 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(@NotNull
                             @NotNull 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

@Nullable
@Nullable 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

@Nullable
default @Nullable MPSCNNGroupNormalizationDataSource initWithCoder(@NotNull
                                                                   @NotNull NSCoder aDecoder)

NS_DESIGNATED_INITIALIZER

label

@Nullable
@Nullable 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()
