Abstract :
Attribute reduction is crucial in concept lattice studies, and its significant theoretical foundation is the judgment of consistent set. Based on improved theorems for judgment of consistent set and the definition of attribute reduction, a new algorithm for attribute reduction is proposed. Comparing to original one, the new algorithm is simple and efficient.
