Closed frequent itemsets

In this article, the authors present a survey of frequent itemsets mining algorithms on transactional database with weighted items over the past twenty years. This research helps researchers to choose the right technical solution when it comes to scale up in big data mining. Finally, the authors give their recommendations and directions for their future research.

The paper proposes an equivalence relation using the closure of itemset to partition the solution set into disjoint equivalence classes and a new, efficient representation of the rules in each class based on the lattice of closed itemsets and their generators. The paper also develops a new algorithm, called MAR-MINSC, to rapidly mine all constrained rules from the lattice instead of mining them directly from the database.

This paper aims to find a structure of frequent itemsets that satisfy the following conditions: they include a subset C10, contain no items of a subset C 11, and have at least an item belonging to subset C21.

The present paper focuses on the discovery of association rules in which the left-handed and right-handed sides contain in two user-supplied maximum single constraints. If the constraints appear on or differ from a lattice of closed itemsets (together with their typically undersized generators and supports) that have been mined and saved once, we quickly extract the corresponding frequent sub one.
