fann_get_bit_fail

(PECL fann >= 1.0.0)

fann_get_bit_fail — The number of fail bits

Description

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() )

Parameters

ann

Neural network resource .

Return Values

The number of bits fail, or false on error.
