Decrease memory usage in high utility mining

I want to decrease the memory usage of EFIM or UPGrowth for high utility mining. Please give me the ideas. Also, can we use these algorithms for incremental mining?

These algorithms are not designed for incremental mining but they could certainly be adapted and it would be interesting from a research perspective to do that.
Actually, UPGrowth is similar to IHUP, which was designed for incremental mining, so you could check the IHUP paper for some ideas. But IHUP and UPGrowth are much slower than EFIM. So if you want to design a fast algorithm for high utility itemset mining in an incremental database, it would be better to base your work on EFIM, in my opinion.
