Re: ClaSp
hello, I want to add a max gap constraint to the clasp algorithm implemented in SPMF to limit the distance between two items, but I don't know how to do it, or I haven't succeeded yet. could someone give me some ideas? Hi, since I am facing a similar problem, did you manage to modify the algorithm ...

Re: mining closed sequential patterns
Directly checking the output of VMSP, I think that the issue is in the algorithm. I got this output (beside other patterns): 1 -1 2 -1 3 -1 4 -1 5 -1 6 -1 #SUP: 12 1 -1 3 -1 4 -1 5 -1 6 -1 #SUP: 11 1 -1 2 -1 4 -1 5 -1 6 -1 #SUP: 11 1 -1 2 -1 3 -1 5 -1 6 -1 #SUP: 11 If it can help, I am using the &qu...

Re: mining closed sequential patterns
Thank you for your answer. Since I did not find the "known limitations" section in the download page, are there any known bugs for the VMSP algorithm? It returned me some sequential patterns (called here A,B,C) such that B and C are subsequences of A (and this already violates the definiti...

mining closed sequential patterns
Good morning, for a project I need to mine closed sequential patterns, so I tested all the algorithms provided in the SPMF library (i.e., ClaSP, CM-ClaSP, CloFAST, CloSpan, BIDE+). Since all these algorithms mine closed sequential patterns, why does BIDE+ report a different number of closed sequenti...
