In this paper, an incremental mining algorithm for efficiently mining high utility itemsets is proposed to handle the above situation.It is based on the concept of the fast-update (FUP) approach, which was originally designed for association mining.Frequent itemset mining is the essential step of data mining process. Further frequent itemset is a primary data obligatory for association rule mining.

The process of updating database continuously is known as incremental data mining. Here is an example given that A, B, C, D are destinations: I think this is a recommender system problem and I studied techniques to approach a solution.
