摘要: We investigate the problem of mining numerical data with Formal Concept Analysis. The usual way is to use a scaling procedure -transforming attributes into binary ones- leading either loss information or efficiency, in particular w.r.t. volume extracted patterns. By contrast, we propose directlywork on more precise and efficient way. For that, notions closed patterns, generators equivalent classes are revisited context. Moreover, two algorithms proposed tested an evaluation involving real-world data, showing quality present approach.
