fann_train_on_file — Trains on an entire dataset, which is read from file, for a period of time

说明

bool fann_train_on_file ( resource $ann , string $filename , int $max_epochs , int $epochs_between_reports , float $desired_error )

Trains on an entire dataset, which is read from file, for a period of time.

This training uses the training algorithm chosen by fann_set_training_algorithm() and the parameters set for these training algorithms.

参数

ann: Neural network resource.
filename: The file containing train data
max_epochs: The maximum number of epochs the training should continue
epochs_between_reports: The number of epochs between calling a user function. A value of zero means that user function is not called.
desired_error: The desired fann_get_MSE() or fann_get_bit_fail(), depending on the stop function chosen by fann_set_train_stop_function()

返回值

Returns TRUE on success, or FALSE otherwise.
