GELU

Gaussian Error Linear Units (GELUs) are rectifiers that are gated by the magnitude of their input rather than the sign of their input as with ReLU variants. Their output can be interpreted as the expected value of a neuron with random dropout regularization applied.

Parameters

This activation function does not have any parameters.

Example

use Rubix\ML\NeuralNet\ActivationFunctions\GELU;

$activationFunction = new GELU();
