Future of Frequent Pattern Mining
Hi,
I'm resending this mail to also include the users list. To wrap up: We
currently have a discussion whether our frequent pattern mining package
should stay in the codebase. The original author suggested to remove the
original implementation and maybe retain the FPGrowth2 implementation.
I'd like to ask our users here on their opionion, is anybody opposed to
removing the frequent pattern mining code from Mahout? Please shout out.

I'm very much in favor of this idea.

I don't think we have to extract the code, people can pull it out of the
0.9 releases sources which are in svn.
We have not heard any opposition from a production users of this code
here, nor has someone stepped up to maintain this code (and we've asked
for the second time), so let's finish what we already aimed for in the
0.9 release and remove it.
I'll prepare a patch.

One thought is to extract the code, publish on github with warnings about
no support. Then if there are requests, we can point them to the GH
archive and tell them to go for it.

+100 to purging this from the codebase. This stuff uses the old MR api and
would have to be upgraded not to mention that this was removed from 0.9 and
was restored only because one user wanted it who promised to maintain it
and has not been heard from.

Hi Sebastian
Thanks for your reply. I agree that makes sense.
I am not familiar enough with the codebase of Mahout, but generally
speaking it might make sense to "modularize" it somehow, such that
algorithms like the fpgrowth code could be downloaded separately
independent of the core codebase.
Thanks
Michael

Hi Michael,
the problem is that currently nodoby is maintaining the fpgrowth code
anymore or working on documentation for it, that's why we consider it to
be a candidate for removal. I don't see much value in keeping algorithms
in the codebase if nobody is maintaining them, answering questions and
providing documentation. If someone opposes here who has that code in
production, that could be a reason to retain it however.
People wanting to use the code in the future can always download Mahout
0.9 which has the current implementation.

what is the alternative and if one would still want to use the "frequent
pattern mining code" in the future, how
would this be possible otherwise?

+100 to purging this from the codebase. This stuff uses the old MR api and
would have to be upgraded not to mention that this was removed from 0.9 and
was restored only because one user wanted it who promised to maintain it
