Re: Sequential Pattern Mining with Multiple supports

Currently, there is no algorithm in SPMF for sequential pattern mining with multiple thresholds but there are some for itemset mining.
Transforming a pattern mining algorithm to handle multiple threshold is usually not so difficult. It would require to read how people have done it in frequent sequential pattern mining and then copy the idea and integrate it to Hirate and Yamana.
I am not familiar with the paper on sequential pattern mining with multiple thresholds but I know that for itemset mining, it is not difficult to do. It just require to use some special tricks such as sorting items according to some order, and then multiple thresholds can be used. I assume that doing it for sequential pattern mining would required to use a similar strategy and thus that it could be adapted for Hirate & Yamana.
But to make sure, it would require to read the papers. Actually, this topic of adding multiple thresholds in Hirate and Yamana could even perhaps be the topic of a short research paper if there is some new challenges, but I am not sure about that (perhaps that it just require a combination of existing ideas rather than some new idea).
