| Abstract: | In order to dealing with the uncertainty in artificial intelligence,a new concept of stochastic type-2 fuzzy set is put forward on the basis of studying type-2 fuzzy set theory.According to the definition of the stochastic type2 fuzzy set,we define mathematic models and algorithms for a kind of normal stochastic type-2 fuzzy set,and analyze its model parameters and shape characteristics.Finally,an instance proves that stochastic type-2 fuzzy set can be used to deal with a great deal of uncertain problems of... |
