Fournier-Viger 2016PHM: Mining Periodic High-Utility
Itemsets
– This paper introduce the concept of periodic patterns in high utility itemset mining.

– The PHM algorithm was presented, which is inspired by HUI-Miner and PFPM.
Wu 2015Mining Closed+ High Utility Itemsets
without Candidate Generation
– This is the first paper on closed high utility itemset mining.

– The LHUI-Miner algorithm and PHUI-Miner algorithm are variation of the FHM algorithm.
Fournier-Viger 2020Mining correlated high-utility itemsets using various measures– This paper aims to find correlated high utility itemsets, that is itemsets that not only have a high utility (importance) but also contains items that are highly correlated. This is to avoid finding patterns that have a high utility but just appear together by chance.
