Beschreibung

float fann_get_bit_fail_limit ( resource $ann )

Returns the bit fail limit used during training.

The bit fail limit is used during training where the stop function is set to FANN_STOPFUNC_BIT.

The limit is the maximum accepted difference between the desired output and the actual output during training. Each output that diverges more than this limit is counted as an error bit. This difference is divided by two when dealing with symmetric activation functions, so that symmetric and not symmetric activation functions can use the same limit.

The default bit fail limit is 0.35.
