Topological Structures and Rule Generation from Data Tables

Abstract

There are many mathematical methods of analyzing data in a form of table and, among them, formal concept analysis, and rough set theory are well-known. Also well-known is that both generate topological structures. In this report, we point out the difference of their topological spaces from a point of view of their approach to data analysis. Finally wee concludes the topology generated from is weaker than that of rough sets.
