The notion of three-way decisions was originally introduced by the needs to explain the
three regions of probabilistic rough sets. Recent studies show that rough set theory is only …

Shadowed sets, proposed by Pedrycz, provide a threeway approximation scheme for
transforming the universe of a fuzzy set into three disjoint areas, ie, elevated area, reduced …
