Output-back fuzzy logic systems and equivalence with feedback neural networks

A new idea, output-back fuzzy logic systems, is proposed. It is proved that outputback fuzzy logic systems must be equivalent to feedback neural networks. After the notion of generalized fuzzy logic systems is defined, which contains at least a typical fuzzy logic system and an output-back fuzzy logic system, one important conclusion is drawn that generalized fuzzy logic systems are almost equivalent to neural networks.
