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
说明
$connection_rate
, int $num_layers
, array $layers
)Creates a standard backpropagation neural network, which is not fully connected using an array of layer sizes.
参数
-
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.
返回值
Returns a neural network resource on success, or FALSE on error.
