FUZZYRULEXT: extraction technique of if/then rules for fuzzy neural nets

User explanation is an important function in artificial intelligence. Experience with expert systems and artificial neural networks (ANN) has shown that the ability to generate explanations is absolutely crucial for user acceptance, mainly in the medical area. ANNs traditionally have had difficulties with generating explanation structures. With this in mind, this paper presents an extraction technique of rules for a fuzzy ANN AND/OR.
