Abstract
The present invention introduces the development of a flexible CPU-AP (Computer Processing Unit-Automata Processor) computing infrastructure for mining hierarchical patterns based on Apriori algorithm. A novel automaton design strategy, called linear design, is described to generate automata for matching and counting hierarchical patterns and apply it on SPM (Sequential Pattern Mining). In addition, another novel automaton design strategy, called reduction design, is described for the disjunctive rule matching (DRM) and counting. The present invention shows performance improvement of AP SPM and DRM solutions and broader capability over multicore and GPU (Graphics Processing Unit) implementations of GSP SPM, and shows that AP SPM and DRM solutions outperform state-of-the-art SPM algorithms SPADE and PrefixSpan (especially for larger datasets).
