Operator matching in fuzzy decision tree based on sound logic

This paper discusses properties of sound logic based on flexible logic, computing model of sound fuzzy logic system, sound probability logic system and sound Luckasiewicz logic system are derived. In the practical application of fuzzy decision tree, algorithm of matching operator in the fuzzy decision tree is improved based on sound logic. Compared with the traditional matching algorithms, the experiments show that the proposed algorithm can obtain a higher accuracy.
