<MPSDeviceProvider>(3) MetalPerformanceShaders.framework <MPSDeviceProvider>(3) NAME
<MPSDeviceProvider> SYNOPSIS
#import <MPSCoreTypes.h> Inherited by MPSKeyedUnarchiver. Instance Methods (id< MTLDevice >) - mpsMTLDevice Detailed Description A way of extending a NSCoder to enable the setting of MTLDevice for unarchived objects When a object is initialized by a NSCoder, it calls -initWithCoder:, which is missing the necessary MTLDevice to correctly initialize the MPSKernel, or MPSNNGraph. If the coder does not conform to MPSDeviceProvider, the system default device will be used. If you would like to specify which device to use, subclass the NSCoder (NSKeyedUnarchiver, etc.) to conform to MPSDeviceProvider so that the device can be gotten from the NSCoder. See MPSKeyedUnarchiver for one implementation of this protocol. It reads files prepared with the NSKeyedArchiver and allows you to set the MTLDevice that the unarchived objects use. Method Documentation - (id <MTLDevice>) mpsMTLDevice Return the device to use when making MPSKernel subclasses from the NSCoder Reimplemented in MPSKeyedUnarchiver.

MPSCNNFullyConnectedGradient(3) MetalPerformanceShaders.framework MPSCNNFullyConnectedGradient(3) NAME
MPSCNNFullyConnectedGradient SYNOPSIS
#import <MPSCNNConvolution.h> Inherits MPSCNNConvolutionGradient. Instance Methods (nonnull instancetype) - initWithDevice:weights: (nullable instancetype) - initWithCoder:device: (nonnull instancetype) - initWithDevice: Additional Inherited Members Detailed Description This depends on Metal.framework Compute the gradient for fully connected layer. Method Documentation - (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.
