Unifying Reducts in Formal Concept Analysis and Rough Set Theory

摘要

Attribute reduction is a fundamental part in different mathematical tools devoted to data analysis, such as, Rough Set Theory and Formal Concept Analysis. These last mathematical theories are closely related and, in this paper, we establish connections between attribute reduction in both frameworks. Mainly, we have introduced a sufficient and necessary condition in order to ensure that the reducts in both theories coincide.
