The key strategy of the three-way decisions theory is to consider a decision-making problem
as a ternary classification one (ie acceptance, rejection and non-commitment). Recently, this …

Pythagorean fuzzy sets (PFSs) as a new generalization of intuitionistic fuzzy sets (IFSs) can
effectively handle uncertain information more flexibly in the process of decision making. As a …

The complexity and impact of many real world decision making problems lead to the
necessity of considering multiple points of view, building group decision making problems in …

Three-way decisions provide a new research perspective for solving decision-making
problems. Under a multiple-criteria environment, this paper proposes a novel decision …

The rough set theory approximates a concept by three regions, namely, the positive,
boundary and negative regions. Rules constructed from the three regions are associated …

A theory of three-way decisions is constructed based on the notions of acceptance, rejection
and noncommitment. It is an extension of the commonly used binary-decision model with an …

Many previous studies on face recognition attempted to seek a precise classifier to achieve
a low misclassification error, which is based on an assumption that all misclassification costs …

Due to the effectiveness and advantages of interval-valued intuitionistic fuzzy sets (IVIFSs) in
evaluating uncertainty and risk, we introduce IVIFSs into loss functions of decision-theoretic …

As a natural extension of three-way decisions with incomplete information, this paper
provides a novel three-way decision model based on incomplete information system. First …

Recommender systems attempt to guide users in decisions related to choosing items based
on inferences about their personal opinions. Most existing systems implicitly assume the …
