Subject RE: [math] Multivariate Gaussian Mixture Model
Date Wed, 11 Jul 2012 16:34:01 GMT

I have created 3 JIRA tickets for the code I plan to submit:  Math-815, 816, and 817.

My employer has given me permission to contribute the code. I am not an expert in the Apache
license. I read It seems that our company is still
allowed to retain copyright, and we give the ASF non-exclusive copyright as well. Is this
correct? My company is also generally requires that I place our name somewhere near the top
of the comments. Does this work for you?

Thank you for the quick reply.  I will create some unit tests and review the submission procedures.
 Hopefully I will submit it in the next week or two.

Dear Jared,

Yes, that would be very nice to have such an addition! Remember to also include unit tests
(refer to the current ones for examples). The best would be to split a submission up into
multiple minor ones, each covering a natural submission (e.g. multivariate Normal distribution
in one submission), and create an issue as described at

If you run into any problems, please do not hesitate to ask on this mailing list.

Cheers, Mikkel.

mixture models, and an expectation maximization fitting class for the mixture model.  I would
like to submit it to Apache Commons Math.  I still have some touching up to do so that they
fit the style guidelines and implement the correct interfaces.  Before I do so, I thought
I would at least ask if the developers of the project are interested in me submitting them.
