Abstract: Concept lattice is an effective tool for rules extraction. First, the rule sets and the general attribute sets are defined under the premise of that all the concepts were known and the lattice structure need not be known in a formal context. Then a rule-generating algorithm of universal application is given, which is a rules extraction method for each type of sample set in the redundant rules set based on the general attribute sets. Furthermore, the related rule subsets can be generated. Finally, the method is used in rules extraction of C-band radio signal, and the experimental results show the method is feasible and effective.
