An Optimal Set of Implications in Triadic Contexts
摘要
In triadic data setting, implications can be extracted in different forms: those introduced by Biedermann (conditional attribute and attributional condition implications) and those introduced by Ganter and Obiedkov (attribute \(\times \) condition, conditional attribute and attributional condition implications). We provide in this paper an optimal set of implications for triadic data, based on pseudo-features, a notion similar to pseudo-intent for dyadic data.
