NAME
MPSCNNNeuronReLUN
SYNOPSIS
#import <MPSCNNNeuron.h>
Inherits MPSCNNNeuron.
Instance Methods
(nonnull instancetype) - initWithDevice:a:b:
(nonnull instancetype) - initWithDevice:
Additional Inherited Members
Detailed Description
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.
The default value of a is 1.0f and the default value of b is 6.0f.
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 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.
