Inference via belief qualified if — Then rules based on compatibility relations and possibility theory
We discuss first the representation of IF A THEN B rules in which the primary and secondary variables, A and B, take on values in some sets of values (single values as special cases). We propose the use of compatibility relations. We assume that with each rule a degree of belief as to its validity is associated. Second, we discuss inference in the sense that knowing a possibility distribution on the values of A, and a compatibility relation representing IF A THEN B, with its degree of belief, we seek an induced possibility distribution on the values of B.
