FANN_GET_ACTIVATION_FUNCTION(3) 					 1					   FANN_GET_ACTIVATION_FUNCTION(3)

fann_get_activation_function - Returns the activation function

SYNOPSIS

       int fann_get_activation_function (resource  $ann, int  $layer, int  $neuron)

DESCRIPTION

	Get the activation function for neuron number neuron in layer number layer, counting the input layer as layer 0.

	It is not possible to get activation functions for the neurons in the input layer.

	The return value is one of the activation functions constants.

PARAMETERS

	      o $ann
		-Neural network resource.

	      o $layer
		- Layer number.

	      o $neuron
		- Neuron number.

RETURN VALUES

       Learning functions constant or -1 if the neuron is not defined in the neural network, or FALSE on error.

fann_create_standard - Creates a standard fully connected backpropagation neural network

SYNOPSIS

       resource fann_create_standard (int  $num_layers, int  $num_neurons1, int  $num_neurons2, [int  $...])

DESCRIPTION

	Creates a standard fully connected backpropagation neural network.

	There  will  be  a  bias neuron in each layer (except the output layer), and this bias neuron will be connected to all neurons in the next
       layer. When running the network, the bias nodes always emits 1.

	To destroy a neural network use the fann_destroy(3) function.

PARAMETERS

	      o $num_layers
		- The total number of layers including the input and the output layer.

	      o $num_neurons1
		- Number of neurons in the first layer.

	      o $num_neurons2
		- Number of neurons in the second layer.

	      o $...
		- Number of neurons in other layers.

RETURN VALUES

	Returns a neural network resource on success, or FALSE on error.
