fann_get_bit_failThe number of fail bits


fann_get_bit_fail(resource $ann): int

The number of fail bits; means the number of output neurons which differ more than the bit fail limit (see fann_get_bit_fail_limit(), fann_set_bit_fail_limit()). The bits are counted in all of the training data, so this number can be higher than the number of training data.

This value is reset by fann_reset_MSE() and updated by all the same functions which also updates the MSE value (e.g. fann_test_data(), fann_train_epoch())



Ressource eines neuralen Netzwerks.
