Frequent Episode Discovery framework is a popular framework in Temporal Data
Mining with many applications. Over the years many different notions of
frequencies of episodes have been proposed along with different algorithms for
episode discovery. In this paper we present a unified view of all such
frequency counting algorithms. We present a generic algorithm such that all
current algorithms are special cases of it. This unified view allows one to
gain insights into different frequencies and we present quantitative
relationships among different frequencies.
