Partial Periodic Frequent Pattern Mining
Partial Periodic-Frequent Patterns in a temporal database are recurring patterns that exhibit partial cyclic repetitions over time. Unlike full periodic-frequent patterns, which require complete cyclic repetitions, partial periodic-frequent patterns capture temporal regularities that may not follow a strict periodicity. These patterns represent recurring behaviors or events within specific time intervals, where the frequency of occurrence varies but still demonstrates a degree of periodicity. The interestingness of a partial periodic-frequent pattern is determined by its periodic ratio, which measures the proportion of cyclic repetitions it exhibits in the database.
