fann_create_sparse

(PECL fann >= 1.0.0)

fann_create_sparseCreates a standard backpropagation neural network, which is not fully connected


説明

fann_create_sparse ( float $connection_rate , int $num_layers , int $num_neurons1 , int $num_neurons2 , int ...$num_neuronsN ) : resource

Creates a standard backpropagation neural network, which is not fully connected.


パラメータ

connection_rate
The connection rate controls how many connections there will be in the network. If the connection rate is set to 1, the network will be fully connected, but if it is set to 0.5 only half of the connections will be set. A connection rate of 1 will yield the same result as fann_create_standard().
num_layers
The total number of layers including the input and the output layer.
num_neurons1
Number of neurons in the first layer.
num_neurons2
Number of neurons in the second layer.
num_neuronsN
Number of neurons in other layers.


返り値

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