讲座简介：

A theory of three-way decision concerns thinking in threes, problem solving in threes, and computing in threes. Symbols-Meaning-Value (SMV) spaces is a fundamental triadic construct for guiding human and machine perception, cognition, and action. In this talk, I will discuss (1) the art and science of three-way decision, (2) the concept of SMV spaces, and (3) the applications of three-way decision and SMV spaces.
