By considering the various of studies on loss functions with three-way decisions, a function based three-way decisions is proposed to generalize the existing models. A “four-level” approach with granular perspective is built, and the existing models can be categorized to a “four-level” framework through different decision criteria. Our work provides a novel “granularity” viewpoint on the current three-way decision researches.
