Three-way decision, as an extension of traditional two-way decision, was proposed by Yao
in 2009, which can effectively avoid unnecessary losses caused by incorrect decisions in the …

In the traditional two-way decision, there are only two kinds of decisions (ie, acceptance and
rejection). It will sometimes pay unnecessary costs when one makes decisions in this way …

As an important extension of the rough set theory, interval-set rough sets provide an effective
method to solve the problem that the objective sets cannot be accurately expressed in the …

Rough set theory is an effective approach to imprecision, vagueness, and uncertainty. This
theory overlaps with many other theories such that fuzzy sets, evidence theory, and statistics …

An information system as a database that expresses relationships between objects and
attributes is an important mathematical model in the field of artificial intelligence. A hybrid …

The tolerance rough set is developed as one of the outstanding extensions of the Pawlak's
rough set model under incomplete information, and the limited tolerance relation is …

Classical rough set theory has been used in analyzing complete information systems, where
all attribute values are available to all objects. However, it cannot cope with the incomplete …

Aiming at the problems of filling missing information and calculating conditional probability
and loss function in incomplete information systems, this paper provides a novel three-way …

Since the rough sets theory based on the double quantification method was proposed, it has
attracted wide attention in decision-making. This paper studies the decision-making …

The tolerance relation based incomplete multigranulation rough set is not able to explore the
incomplete ordered decision systems. To solve such problem, similarity dominance relation …
