Modeling and Mining Optimal Patterns Using Dynamic CSP
Willy Ugarte, Patrice Boizumault, Samir Loudni, Bruno Crémilleux · 2015
We introduce the notion of Optimal Patterns (OPs), defined as the best patterns according to a given user preference, and show that OPs encompass many data mining problems. Then, we propose a generic method based on a Dynamic Constraint Satisfaction Problem to mine OPs, and we show that any OP is characterized by a basic constraint and a set of constraints to be dynamically added. Finally, we perform an experimental study comparing our approach vs adhoc methods on several types of OPs.
