Knowledge space rough set
WebApr 10, 2015 · The vague set, as well as the rough set, focuses on finding the boundaries of a vague concept and neglects how to construct a defined set with many granules in current knowledge space as an approximation concept of the vague concept. Fuzzy set is a very successful approach to vagueness. WebRough set theory, introduced by Zdzislaw Pawlak in the early 1980s [11, 12], is a new mathematical tool to deal with vagueness and uncertainty.
