With the developments of three historical stages on three-way decisions (3WD), this paper
introduces the development track and evolution process of 3WD. Firstly, the historical …

The notion of three-way decisions (3WD), introduced by Yiyu Yao in 2009, was initially
intended as a means to interpret classification/decision rules induced in probabilistic rough …

By thinking, information processing and decision-making in threes, the idea, theory and
methods of three-way decision have been successfully applied to various domains …

With the fast developments of three-way decisions (3WD), this paper systematically
summarizes the development track and evolution process of 3WD in recent decades. Firstly …

Abstract Three-way decisions (3WDs) based on decision-theoretic rough set (DTRS), as a
crucial theory in the field of granular computing, have received extensive attention …

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 …

A theory of three-way decisions is formulated based on the notions of three regions and
associated actions for processing the three regions. Three-way decisions play a key role in …

In this paper, we present a composite framework of sequential three-way decisions to deal
with hybrid data based on the fusion of different granularities. According to the top-down …

The three-way decision (3WD) using probabilistic rough set (PRS) is constructed based on
the probabilistic thresholds, and the 3WD using decision-theoretic rough set (DTRS) can …

A theory of three-way decisions is formulated based on the notions of three regions and
associated actions for processing the three regions. Inspired by the theory of three-way …
