The signature segments a sequence of itemsets, so that the set of items that occurs in every segment is the largest. The sky-signature is a model that summarizes sequence recurrences at all time scales, whereas the signature gives the recurrences at a single time scale. The sky-signature is based on skyline patterns.
The format of the input is a list of list of integers. Each inner list a transaction. For example, the input [[1,2,3], [4,5], [1,6], [1,2,8]] represents a sequence of 4 transactions. The first transaction contains the itemset (1,2,3).
The available algorithms are patterngrowth, dynamicprogramming, dynamicprogrammingapproximate, hybrid.
