The group proposes and evaluates algorithms for artificial intelligence and machine learning, data mining and big data analysis. Two specific topics that have been and are being worked on are on advanced algorithms in sequential pattern and rule mining and on the development of algorithms for sequential pattern and rule mining from sequence databases.
