fann_set_activation_function_layer
(PECL fann >= 1.0.0)
fann_set_activation_function_layer — Sets the activation function for all the neurons in the supplied layer.
说明
bool fann_set_activation_function_layer
( resource
$ann
, int $activation_function
, int $layer
)Set the activation function for all the neurons in the layer number layer, counting the input layer as layer 0.
It is not possible to set activation functions for the neurons in the input layer.
