A ReLU node with parameter a provided independently for each feature channel For each pixel, applies the following function:



    f(x) = x                if x >= 0


         = aData[i] * x     if x < 0,  i is the index of the feature channel
@param      sourceNode              The MPSNNImageNode representing the source MPSImage for the filter
@param      aData                   An array of single precision floating-point alpha values to use

- (nonnull instancetype) initWithSource: (MPSNNImageNode *__nonnull) sourceNode(NSData *__nonnull) aData

Init a node representing a MPSCNNNeuronTanH kernel For each pixel, applies the following function:

f(x) = x                if x >= 0


     = aData[i] * x     if x < 0,  i is the index of the feature channel

Parameters:

sourceNode The MPSNNImageNode representing the source MPSImage for the filter
aData An array of single precision floating-point alpha values to use

Returns:

A new MPSNNFilter node for a MPSCNNNeuronTanH kernel.
