In order to do so, a new direct formula is first developed to generate the fuzzy rules from the premise part in FNN. This direct formula not only guarantees a one to one mapping that maps the fuzzy membership functions onto the fuzzy rules, but also alleviates the coding effort during hardware implementation. It is further elaborated that the FNN with non-overlapped BPMF's has the advantage of faster on-line training which requires less computation time, but at the cost of more memory requirement to store the fuzzy rules.
