#import <MPSCNNConvolution.h>

Inherits MPSCNNConvolutionGradient.


(nonnull instancetype) - initWithDevice:weights:
(nullable instancetype) - initWithCoder:device:
(nonnull instancetype) - initWithDevice:

This depends on Metal.framework Compute the gradient for fully connected layer.

- (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 MPSKernel object, or nil if failure.

Reimplemented from MPSCNNConvolutionGradient.

- (nonnull instancetype) initWithDevice: (nonnull id< MTLDevice >) device

Standard init with default properties per filter type

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.

Reimplemented from MPSCNNConvolutionGradient.

- (nonnull instancetype) initWithDevice: (nonnull id< MTLDevice >) device(nonnull id< MPSCNNConvolutionDataSource >) weights

Initializes a convolution gradient (with respect to weights and bias) object.

Parameters:

device The MTLDevice on which this MPSCNNConvolutionGradient filter will be used
weights A pointer to a object that conforms to the MPSCNNConvolutionDataSource protocol. Note that same data source as provided to forward convolution should be used.

Returns:

A valid MPSCNNConvolutionGradient object or nil, if failure.

Reimplemented from MPSCNNConvolutionGradient.
