A Fast Approach to Explore the Reduction of Concept Lattice

The concept lattice is useful in knowledge processing and data analyzing. By reducing lattice, it can get the process more efficiently and the work will be simpler. In this paper, a kind of composing relation between reduct and relative necessary attributes is proposed, then is proved, and a novel approach to explore the reduction of concept lattice is presented. Since we avoid computing all of the concepts of the formal context, distinguishable matrix and distinguishable function, it is a fast and sententious approach.
