fann_create_sparse_array
(PECL fann >= 1.0.0)
fann_create_sparse_array — Creates a standard backpropagation neural network, which is not fully connected using an array of layer sizes
説明
fann_create_sparse_array
( float $connection_rate
, int $num_layers
, array $layers
) : resource
Creates a standard backpropagation neural network, which is not fully connected using an array of layer sizes.
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.
layers
- An array of layer sizes.
返り値
Returns a neural network resource on success, or false
on error.
