A new geometric construction method of Pythagorean fuzzy entropy
The variation law of Pythagorean fuzzy entropy is analyzed from the perspective of spatial geometric meaning.According to the characteristics of graphic structure,the concept of isentropic arc is proposed by considering the influence of intuition and fuzziness of Pythagorean fuzzy set on entropy.A new Pythagorean fuzzy entropy calculation formula is constructed,the new entropy formula not only satisfies the axiomatic definition,but also can intuitively compare the size of entropy from the geometry of Pythagorean fuzzy sets.
