Detailed Description

       This depends on Metal.framework  Specifies the parametric ReLU neuron
       filter. For each pixel, applies the following function: f(x_i) = x_i,
       if x_i >= 0 = a_i * x_i if x_i < 0 i in [0...channels-1] i.e.
       parameters a_i are learned and applied to each channel separately.
       Compare this to ReLu where parameter a is shared acorss all channels.
       See https://arxiv.org/pdf/1502.01852.pdf for details.

Method Documentation

   - (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 MPSCNNKernel.

   - (nonnull instancetype) initWithDevice: (nonnull id< MTLDevice >)
       device(const float *_Nonnull) a(NSUInteger) count
       Initialize the PReLU neuron filter

       Parameters:
           device The device the filter will run on
           a Array of floats containing per channel value of PReLu parameter
           count Number of flaot values in array a. This usually corresponds
           to number of output channels in convolution layer

       Returns:
           A valid MPSCNNNeuronPReLU object or nil, if failure.
