Re: FCHM BOND with Volume

Hi,
Thanks for using SPMF. I took a bit of time to answer because I was abroad.
Yes, the bond is a simple measure but the concept is quite interesting to find items that appear often together.
About translating patterns into volumes of sales, I do not know any algorithms that would specifically do this and I have never thought about this idea.
If we have an itemset {a1, a2 ... an} the FCHM bond algorithm can know:
- the support of a1
- the support of a2
- ...
- the support of an
- the support of {a1, a2 ... an}
- the bond of {a1, a2 ... an}
Using such information, various measures can be derived such as the bond. But how to calculate volumes? I don't know.
If we see this as a task of prediction, then maybe that some prediction models could be trained using the patterns?
Best regards,
