fann_set_callback — Sets the callback function for use during training

fann_set_callback ( resource $ann , callable $callback ) : bool

Sets the callback function for use during training. It means that it is called from fann_train_on_data() or fann_train_on_file().

ann

Ресурс (resource) нейронной сети.

callback

The supplied callback function takes following parameters:

ann - The neural network resource
train - The train data resource or null if called from fann_train_on_file()
max_epochs - The maximum number of epochs the training should continue
epochs_between_reports - The number of epochs between calling this function
desired_error - The desired fann_get_MSE() or fann_get_bit_fail(), depending on the stop function chosen by fann_set_train_stop_function()
epochs - The current epoch

The callback should return true. If it returns false, the training will terminate.

Возвращает true в случае успешного выполнения, или false в противном случае.

fann_train_on_data() - Обучение на всем объеме данных на временном интервале
