Extraction efficace des représentations condensées de motifs: Applications aux skypatterns et aux clusterings conceptuels
Abstract
Condensed representations of patterns offer an elegant way to represent solution sets compactly,
while minimizing the redundancy and the number of patterns. This approach has been
mainly developed in the context of the frequency measure and there are very few works addressing
other measures. We propose a generic framework based on constraint programming
to efficiently mine adequate condensed representations of patterns w.r.t. a set of measures.
For this, we introduce a new global constraint with a complete polynomial filtering. We show
how this constraint can be exploited in association with Pareto dominance constraints to mine
skypatterns and conceptual clustering. Experiments performed on standard datasets show the
efficiency of our approach and its significant advantages over existing approaches.
