Abstract :
Rough set theory is an important tool to deal with imprecise, uncertainty and fuzzy information, and has gained great success in machine learning, data mining and intelligent data analysis. When it was proposed, many researchers worked on it in different views such as constructive methods, algebraic methods, formal concept analysis, and etc. We analyze it in view of entropy theory, and present a new concept - knowledge entropy. We discuss properties of it and apply it to discuss basic concepts in rough set theory. From the analysis, we construct a mapping between knowledge entropy theory and rough set theory, and we also hope to find effective algorithms by the application of it.
