fann_save

(PECL fann >= 1.0.0)

fann_save — Saves the entire network to a configuration file

Description

function fann_save(resource $ann, string $configuration_file): bool

Saves the entire network to a configuration file.

The configuration file contains all information about the neural network and enables fann_create_from_file() to create an exact copy of the neural network and all of the parameters associated with the neural network.

These three parameters (fann_set_callback(), fann_set_error_log(), fann_set_user_data()) are NOT saved to the file because they cannot safely be ported to a different location. Also temporary parameters generated during training like fann_get_MSE() is not saved.

Parameters

ann

Neural network resource.

configuration_file

The configuration file path.

Return Values

Returns true on success, or false otherwise.
