| Abstract: | Formal concept analysis is a powerful tool for data analysis in machine learning, data mining, knowledge discovery and information retrieval. By study of the attribute reduction of concept lattices, the judgment theorems of core attribute, absolute unnecessary attribute and relative necessary attribute are proposed, on this base, a method for fast seeking of attribute reduction of formal concept lattices is given. |
| Keywords: | formal concept concept lattices attribute reduction |
