Special Session on Interval Uncertainty WCCI 2022

This special session is for the FUZZ-IEEE 2022 conference which will be held as part of the 2022 IEEE World Congress on Computational Intelligence IEEE WCCI 2022 in Padua, Italy, on July 18-23, 2022. IEEE WCCI 2022 is the world's largest technical event on computational intelligence, featuring the three flagship conferences of the IEEE Computational Intelligence Society (CIS):

Scope and Aim

Interval uncertainty -- when we only know the interval containing the actual value of a quantity -- is closely related to fuzzy techniques. For example, if we want to know how the fuzzy uncertainty of the inputs propagates through the data processing algorithm, then the usual Zadeh's extension principle is equivalent to processing α-cuts (intervals) for each level α.

Yet another relation between interval and fuzzy techniques is that the traditional fuzzy techniques implicitly assume that experts can describe their degree of certainty in different statements by an exact number. In reality, it is more reasonable to expect experts to provide only a rage (interval) of possible values -- leading to interval-valued fuzzy techniques that, in effect, combine both types of uncertainty.

These relations between intervals and fuzzy computations is well known, but often, fuzzy researchers are unaware of the latest most efficient interval techniques and thus use outdated less efficient methods. The main objectives of this session are:
