Class MPSCNNNeuronReLU

  • All Implemented Interfaces:
    NSCoding, NSCopying, NSSecureCoding, NSObject
    public class MPSCNNNeuronReLU
extends MPSCNNNeuron
    MPSCNNNeuronReLU [@dependency] This depends on Metal.framework Specifies the ReLU neuron filter. For each pixel, applies the following function: f(x) = x, if x >= 0 = a * x if x < 0 This is called Leaky ReLU in literature. Some literature defines classical ReLU as max(0, x). If you want this behavior, simply pass a = 0 API-Since: 10.0

        Description copied from class: MPSCNNKernel
        Standard init with default properties per filter type
        Overrides:
        initWithDevice in class MPSCNNNeuron
        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.

        Deprecated.
        Initialize the ReLU neuron filter
        Parameters:
        device - The device the filter will run on
        a - Filter property "a". See class discussion.
        Returns:
        A valid MPSCNNNeuronReLU object or nil, if failure. API-Since: 10.0 Deprecated-Since: 12.0

                                            @NotNull java.lang.Object device)
        Description copied from class: MPSCNNNeuron
        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 MPSCNNNeuron
        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.

      • _supportsSecureCoding

        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.
        Specified by:
        _supportsSecureCoding in interface NSSecureCoding
        Overrides:
        _supportsSecureCoding in class MPSCNNNeuron

        Description copied from class: MPSCNNNeuron
        Initialize the neuron filter with a neuron descriptor.
        Overrides:
        initWithDeviceNeuronDescriptor in class MPSCNNNeuron
        Parameters:
        device - The device the filter will run on.
        neuronDescriptor - The neuron descriptor. For the neuron of type MPSCNNNeuronTypePReLU, the neuron descriptor references an NSData object containing a float array with the per feature channel value of PReLu parameter and, in this case, the MPSCNNNeuron retains the NSData object.
        Returns:
        A valid MPSCNNNeuron object or nil, if failure. API-Since: 11.3
