Abstract

In this paper we present an efficient algorithm, called DSPM, for mining all frequent subgraphs in large set of graphs. The algorithm explores the search space in a DFS fashion, while generating candidates in advance to each mining phase just like the Apriori algorithm does. It combines the candidate generation and anti monotone pruning into one efficient operation thanks to the unique mode of exploration. DSPM efficiently enumerates all frequent patterns by using diagonal search, which is a general scheme for designing effective algorithms for hard enumeration problems. Our experiments show that DSPM has better performance, from several aspects, than the current state of the art - gSpan algorithm.
