Three-way decision is about thinking, problem-solving, and computing in threes or through
triads. Its philosophy and practice of triadic thinking appear everywhere. In particular, there …

The theory of three-way decision is about a philosophy of thinking in threes, a methodology
of working with threes, and a mechanism of processing in threes. We approach a whole …

The underlying philosophy of three-way decision is thinking in threes, namely,
understanding and processing a whole through three distinct and related parts. One can …

Based on results from cognitive science, this paper examines the two fields of three-way
decision and granular computing, as well as their interplay. The ideas from one field shed …

By applying the principles of three-way decision as thinking in threes, in this paper I
introduce a conceptual model of data science in three steps. First, I examine examples of …

A trisecting-and-acting model explains three-way decisions (3WD) in terms of two basic
tasks. One task is to divide a universal set into three pair-wise disjoint regions called a …

A theory of three-way decision concerns the art, science, and practice of thinking, problem
solving, and information processing in threes. It explores the effective uses of triads of three …

Abstract Ideas of three-way decisions proposed by Yao come from rough sets. It is well
known that there are three basic elements in three-way decisions theory, which are ordered …

Dual‐process theories hold that there are two distinct processing modes available for many
cognitive tasks: one (type 1) that is fast, automatic and non‐conscious, and another (type 2) …

Abstract TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) uses a pair
of a positive ideal solution and a negative ideal solution as two reference points to rank a set …
