Let's start with a use case... I just happen to have one :-)
I was looking at the PMML specification and noticed that the Data Mining
Group has a nice interoperability program:
http://www.dmg.org/v4-1/Interoperability.html
They have example models and expected output that we can use to validate
our work and and demonstrate interoperability. Maybe we could start by
picking one simple model type and work towards passing DMG Model
Verification.

an use to validatioOk ;) I'll write news asap I have some results!
Btw Marty now I don't have a real use case, I'm just curios to do something
with Mahout more interesting than some examples!

THe jpmml stuff seems reasonable as well. Basically, they use jax to
generate gobs of classes and then cherry-pick structures that they need.
Logistic regression can be a special case of neural nets. There is also (I
think) a specific PMML structure for them.

I'd work on model import before export. It seems to me that mahout has
the scalable execution platform. Being able to import a model might be
nice for cross-validation/QA against a model developed on a less scalable
platform.
Makes sense to me. Import should be relatively easy. Have a look at the
Weka converter and the Lucene one.

Hi All,
sorry for the delay!
I see mahout and for me it's very good :)
If you have some request like PMML I can try to add functionality
and
add
request by github!
Btw for me the only package that is a little mess is
https://github.com/apache/mahout/tree/trunk/math/src/main/java/org/apache/mahout/math
,
is it really used?

Sounds fantastic.
File a JIRA with suggested improvements. Go for it!

Hi Grant,
Ok maybe i can start to code cleanup and refactoring some parts in
Mahout
to became more confident with the code.
I have spent many years to do refactoring for huge, and sometimes
old,
java
project.
After that if my interest grow up I can help to add some features
like
PMML!

Ok thanks Grant,
i already see that link and before the link
https://issues.apache.org/jira/secure/IssueNavigator.jspa?reset=true&jqlQuery=labels+%3D+MAHOUT_INTRO_CONTRIBUTEdoesn't
work!
Btw all bugs listed in that link are closed or resolved.. so I
thinked
to
write in the mailing list
Ah, yeah, would be good for us to go through and mark some more
as
INTRO.
Are there particular things you are interested in? In general,
we
are
focused on code cleanup and documentation as we try to get to a
1.0
release, so contributions that make Mahout easier/cleaner to use
would
be
helpful. I also think refactorings that make it easier to use
Mahout
programmatically would be good. If you have access to a cluster,
testing/running at scale would be useful too.
I could also see us adding support for PMML, which seems to have
some
traction as an interoperability format, but that is just my 2
cents.
