Class MPSNNForwardLoss

  • All Implemented Interfaces:
    NSCoding, NSCopying, NSSecureCoding, NSObject
    public class MPSNNForwardLoss
extends MPSCNNKernel
    MPSNNForwardLoss [@dependency] This depends on Metal.framework. The MPSNNForwardLoss filter specifies a version of the loss filter which separates the forward computation from the gradient computation. In order to compute gradients for the loss filter use @ref MPSNNLossGradient filter and in order to start the gradient computation of an arbitrary image use the @ref MPSNNInitialGradient filter. NOTE: This filter does not support non-default offset or cliprects and setting them to other than default values will result in undefined results.

        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.

        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.
