Detailed Description

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

Method Documentation

  - (nonnull instancetype) initWithDevice: (nonnull id< MTLDevice >) NS_DESIGNATED_INITIALIZER
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 MPSKernel.

  - (nonnull instancetype) initWithDevice: (nonnull id< MTLDevice >) device(float) NS_DESIGNATED_INITIALIZER
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.
