(nullable instancetype) - initWithCoder:device:
This depends on Metal.framework Specifies the filter for computing
the gradient of the dilated max pooling filter. For details see comments on
MPSCNNPoolingMaxGradient.
- (nullable instancetype) initWithCoder: (NSCoder
*__nonnull) aDecoder(nonnull id< MTLDevice >) device
NSSecureCoding compatability See
MPSKernel::initWithCoder.
Parameters:
aDecoder The NSCoder subclass with your serialized
MPSCNNPoolingMaxGradient
device The MTLDevice on which to make the
MPSCNNPoolingMaxGradient
Returns:
A new MPSCNNPoolingMaxGradient object, or
nil if failure.
Reimplemented from MPSCNNPoolingGradient.
- (nonnull instancetype) initWithDevice: (nonnull id<
MTLDevice >) device(NSUInteger) kernelWidth(NSUInteger)
kernelHeight(NSUInteger) dilationRateX(NSUInteger) dilationRateY(NSUInteger)
strideInPixelsX(NSUInteger) strideInPixelsY
Initialize a MPSCNNDilatedPoolingMaxGradient pooling
filter
Parameters:
device The device the filter will run on
kernelWidth The width of the kernel. Can be an odd or even value.
kernelHeight The height of the kernel. Can be an odd or even value.
dilationRateX The dilation rate in the x dimension.
dilationRateY The dilation rate in the y dimension.
strideInPixelsX The output stride (downsampling factor) in the x
dimension.
strideInPixelsY The output stride (downsampling factor) in the y
dimension.
Returns:
A valid MPSCNNDilatedPoolingMax object or
nil, if failure.
