COFI-tree Mining: A New Approach to Pattern Growth with Reduced Candidacy Generation

  title={COFI-tree Mining: A New Approach to Pattern Growth with Reduced Candidacy Generation},
  author={Osmar R. Za{\"i}ane and Mohammad El-Hajj},
Existing association rule mining algorithms suffer from many problems when mining massive transactional datasets. Some of these major problems are: (1) the repetitive I/O disk scans, (2) the huge computation involved during the candidacy generation, and (3) the high memory dependency. This paper presents the implementation of our frequent itemset mining algorithm, COFI, which achieves its efficiency by applying four new ideas. First, it can mine using a compact memory based data structures… CONTINUE READING
