fann_get_bit_fail — The number of fail bits
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.
Neural network resource.
The number of bits fail, or
FALSE on error.
