public class MPSCNNMultiplyGradient
extends MPSCNNArithmeticGradient

MPSCNNMultiplyGradient [@dependency] This depends on Metal.framework.

Specifies the multiplication gradient operator. This arithmetic gradient filter requires the following inputs: gradient image from the previous layer (going backwards) and either the primary or the secondary source image from the forward pass. You will need a separate filter for the primary and secondary source images.

Without broadcasting, the arithmetic multiply gradient operation is an element-wise multiplication operation between the gradient image from the previous layer (going backwards) and: - The secondary source image from the forward pass for the primary source filter (for x * y, d/dx(x * y) = y). - The primary source image from the forward pass for the secondary source filter (for x * y, d/dy(x * y) = x).

Setting the broadcasting parameters results in a reduction operation (sum) across all of the applicable broadcasting dimensions (rows, columns, feature channels, or any combination thereof) to produce the destination image of the size that matches the primary/secondary input images used in the forward pass.

initWithCoder

public MPSCNNMultiplyGradient initWithCoder(NSCoder aDecoder)

Description copied from interface: NSCoding

NS_DESIGNATED_INITIALIZER

Specified by:

initWithCoder in interface NSCoding

Overrides:

initWithCoderDevice

public MPSCNNMultiplyGradient initWithCoderDevice(NSCoder aDecoder,
                                                  java.lang.Object device)

Description copied from class: MPSCNNGradientKernel

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 MPSCNNArithmeticGradient

Parameters:

aDecoder - The NSCoder subclass with your serialized MPSKernel

device - The MTLDevice on which to make the MPSKernel

Returns:

A new MPSKernel object, or nil if failure.

initWithDevice

public MPSCNNMultiplyGradient initWithDevice(java.lang.Object device)

Description copied from class: MPSCNNGradientKernel

Standard init with default properties per filter type

Overrides:

initWithDevice in class MPSCNNArithmeticGradient

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.

initWithDeviceIsSecondarySourceFilter

public MPSCNNMultiplyGradient initWithDeviceIsSecondarySourceFilter(MTLDevice device,
                                                                    boolean isSecondarySourceFilter)

Initialize the multiplication gradient operator.

Parameters:

device - The device the filter will run on.

isSecondarySourceFilter - A boolean indicating whether the arithmetic gradient filter is operating on the primary or secondary source image from the forward pass.

Returns:

A valid MPSCNNMultiplyGradient object or nil, if failure.

public boolean _supportsSecureCoding()

Description copied from interface: NSSecureCoding

This property must return YES on all classes that allow secure coding. Subclasses of classes that adopt NSSecureCoding and override initWithCoder: must also override this method and return YES. The Secure Coding Guide should be consulted when writing methods that decode data.
