The use of sequential pattern mining to predict next

The task of sequential pattern mining is to identify frequent sequences, where frequent is defined as having support above a user-defined threshold. In this paper, we will refer to frequent sequences mined from data-sequences as mined sequential patterns, and we will refer to a patient's data-sequence (the temporally-ordered history of all
