Recent studies have proposed different methods for mining frequent episodes. In this work, we study the problem of mining closed episodes based on minimal occurrences. We study the properties of minimal occurrences and design effective pruning techniques to prune non-closed episodes. An efficient mining algorithm Clo-episode is proposed to mine all closed episodes following a breadth-first search order and integrating the pruning techniques. Experimental results demonstrate the efficiency of our mining algorithm and the compactness of the mining result set. © 2010 Springer-Verlag Berlin Heidelberg.
