Interval Valued Intuitionistic Fuzzy Sets with Parameters and its Application in Pattern Recognition
带参数区间值直觉模糊集及其在模式识别中的应用

The concept of interval-valued intuitionistic fuzzy sets with paramctcrs(IVIFSP) was first introduccd,and a series of IVIFSP were presented. Based on the degree of membership and the degree of non-membership, this paper focused on the construction of interval-valued intuitionistic fuzzy sets with single-parameter. Finally, parameter ectuation with critical point between any two patterns was constructed, and the critical point was proved to be theoretically effecfive in analyzing the result of pattern recognition. The results of pattern recognition simulation show that the method of IVIFSP is more flexible than that of the traditional intuitionistic fuzzy sets.
