fann_get_bit_fail — The number of fail bits

说明

int fann_get_bit_fail ( resource $ann )

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())

参数

ann: Neural network resource.

返回值

The number of bits fail, or FALSE on error.
