Inherits MPSCNNNeuron.


(nonnull instancetype) - initWithDevice:a:b:
(nonnull instancetype) - initWithDevice:

This depends on Metal.framework Specifies the ReLUN neuron filter. For each pixel, applies the following function: f(x) = [ x , x >= 0 [ a * x, x < 0 [ b , x >= b As an example, the TensorFlow Relu6 activation layer can be implemented by setting the parameter b to 6.0f: https://www.tensorflow.org/api_docs/cc/class/tensorflow/ops/relu6.

- (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 MPSCNNNeuron.

- (nonnull instancetype) initWithDevice: (nonnull id< MTLDevice >) device(float) a(float) b

Initialize a ReLUN neuron filter

Parameters:

device The device the filter will run on
a Filter property 'a'. See class discussion.
b Filter property 'b'. See class discussion.

Returns:

A valid MPSCNNNeuronReLUN object or nil, if failure.
