A note on fuzzy-transform approximation of fuzzy numbers

Abstract: A possibilistic representation of fuzzy numbers/intervals can be obtained in terms of a fuzzy distribution function (the average of the possibility and necessity functions). The fuzzy distribution function is monotonic non decreasing upper-semicontinuous and there exists a simple one-to-one correspondence between the space of such functions and the space of fuzzy numbers, i.e., with normal, upper semicontinuous quasi concave membership function. As a consequence, the monotonic F-transform approximation of the … Show more

“…Further research involves some theoretical aspects about several topics: arithmetic operations: using an approach similar to probabilistic arithmetic, which is based on convolutions with density functions (as in [32] and [26], [20]), we will try to express fuzzy arithmetic in terms of AC functions, as we have done for scalar multiplication and addition in subsection 2.1. This approach has been extensively addressed by developing a very e¢ cient software like the packages "distr" and "distrEx" in R language ( [23]); membership estimation through observations (see for example [15] and [7]); possible metrics on ACFs that focuse on useful topological structures (see for example [31] and [35]); ACF approximation through F-transform: the ACF-representation based on monotonic functions eases the search of approximation methods and algorithms (as in [3] and [4]);…”
