Hello everyone,

This is to let you know that I have updated the SPMF data mining software to version 0.82.

This is a minor version. The main difference with 0.81 is that I have fixed a bug in my SPAM algorithm implementation. The bug occurred when the minsup parameter was set to 0. I'm thankful to D. Bhatt who has reported the bug to me.

To fix the bug, you can download the new version. Or, it is possible to fix the bug manually by replacing the following line in the file AlgoSPAM.java :

minsup = (int)(minsupRel * sequencesSize.size());

with:

minsup = (int)(minsupRel * sequencesSize.size());
        if(minsup ==0){
            minsup =1;
        }

That's it.

Besides that, I have been quite busy lately so I did not have time yet to implement some new algorithms. But I will continue improving the software when I have some free time and add some new algorithms. This will be for the next version.

By the way, I'm glad that the counter on the website indicates that there is almost 22,000 hits on the website since two years. Last January the counter showed 15,000. So that means that there was 7000 hits just during the last six months, which is a great increase.

Thanks to all of you,

Philippe
