PFPM define a minimum itemset length
Posted by: Sandra

Hello,

I'm using the PFPM algorithm.

I want to define a minimum and a maximum length of the output itemsets. At the moment the algorithm works with minimum and maximum periods and their average. The results are datasets with any length.

In my case I have to define that for example a itemset has to be a minimum length of 4 items and a maximum of 10 items.

Is there a solution?

Best regards,
Sandra

Hello,

Currently, this feature has not been implemented. But it is not difficult to implement that feature. So I will do it tomorrow. Then, I will update the software and source code on the website, and let you know here when it is done.

Best regards,

Philippe

Hello again,

I have uploaded the new version of SPMF to the website (2.17). You can now specify the minimum pattern length and maximum pattern length for the PFPM algorithm.

Best regards,

Philippe
