The performance study shows that mining periodic-frequent patterns with PF-tree is time and memory efficient and highly scalable as well. We use an efficient tree-based data structure, called Periodic-frequent pattern tree (PF-tree in short), that captures the database contents in a highly compact manner and enables a pattern growth mining technique to generate the complete set of periodic-frequent patterns in a database for user-given periodicity and support thresholds. In this paper, we introduce a novel concept of mining periodic-frequent patterns from transactional databases. A frequent pattern can be said periodic-frequent if it appears at a regular interval given by the user in the database. Temporal periodicity of pattern appearance can be regarded as an important criterion for measuring the interestingness of frequent patterns in several applications. In many real-world scenarios it is often sufficient to mine a small interesting representative subset of frequent patterns. Since mining frequent patterns from transactional databases involves an exponential mining space and generates a huge number of patterns, efficient discovery of user-interest-based frequent pattern set becomes the first priority for a mining algorithm.
