Graph Pattern Mining Conclusion • Lots of sophisticated algorithms for mining frequent graph patterns: MoFa, gSpan, FFSM, Gaston, . . . • But: number of frequent patterns is exponential • This implies three related problems: very high runtimes resulting sets of patterns hard to interpret minimum support threshold hard to set.

Our experiments show that the proposed approach and the graph mining methods gSpan, Gaston, MoFa, and FFSM can find all of the active substructures correctly when there is no noise (p n = 0). However, an increase in the probability of noise results in a dramatic performance decrease in the graph mining methods gSpan, Gaston, MoFa, and FFSM.

Summary. A core problem of approaches to frequent graph mining, which are based on growing subgraphs into a set of graphs, is how to avoid redundant search. ... [14] is a member of this family, and that MoSS/MoFa [1, 3] is implicitly based on a different member, which I …

class of algorithms represents molecules as graphs and then searches for frequent subgraphs in the molecule database. All known graph based data mining algorithms rely on one of the two wellknown frequent itemset mining algorithms, Apriori [1] or Eclat [11]. Examples are MoFa [2], FSG [6], ∗0780385667/04/ c 2004 IEEE.

It remains unclear, how the algorithms work on bigger/other graph databases and which of their distinctive features is best suited for which database. We have reimplemented the subgraph miners MoFa, gSpan, FFSM, and Gaston within a common code base and with the same level of programming expertise and optimization effort.

This page describes mining for molecules may be represented by molecular graphs this is strongly related to graph mining and structured data main problem is how to represent molecules while discriminating the data instances.
