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

ReturnType fann_create_sparse_array ( float $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.
