You can check the new paper of my collaborator in TKDE:
Truong, T., Duong, H., Le, B., Fournier-Viger, P. (2018). Efficient Vertical Mining of High Average-Utility Itemsets based on Novel Upper-Bounds . IEEE Transactions on Knowledge and Data Engineering (TKDE), to appear.
He presents a new average utility mining algorithm which is faster than the most recent algorithms for this problem usin
