There has been strong support to officially merge Machine Learning with Cross Validated. Later this week, we will be migrating questions from the Machine Learning and making it an official part of this site.

I re-posted the Machine Learning announcement as an answer below, for your reference.

Be prepared to integrate these questions and this subject into your site. You can close questions that are blatantly off topic, but be mindful — this is a growing scope of questions looking for a best fit. We want to make every effort to accommodate the community on this site, and err towards being open-minded and make adjustments to accommodate the subject.

To all: Most of these questions likely will not need any action from our community. Consider using the list provided by Rebecca as a guide to a collection of threads you might wish to read in the near future; I hope you enjoy them. As you catch up, your help would be much appreciated in identifying any (near) duplicates, as well as any that might possibly be off topic. When you run across such a situation, please just click on the flag link beneath the question to let a moderator know about it. Thank you! –  whuber Feb 22 '12 at 21:27
Now all we need is AI to be included and everybody can be very happy –  Ivo Flipse Feb 22 '12 at 22:18
@IvoFlipse and change the name of it to ML.SE ..... ;-) –  tdc Feb 23 '12 at 10:02

This is a re-post of the Machine Learning announcement (since it is still in private beta):

The Future of Machine Learning as a Stack Exchange Subject

The "Machine Learning" Stack Exchange started with a proposal in Area 51. A groups of experts propose a subject they felt were not found on the Stack Exchange Network. In the meantime, you have a Stats SE ("Cross Validated") who claim that "Machine Learning" is explicitly on topic for that site. Still, the supporters of the ML site wonders if all machine learning topics are a good fit for Cross Validated.

So what to do? We're not experts in this domain, so we let the proposal continue to see how it develops in actual practice. As it turns out, about 85-95% of the questions being asked are a perfect fit for Cross Validated. Even now, there is still widespread support to welcome the Machine Learning questions on their site.

Should Machine Learning SE be merged with CrossValidated?

So be it. Around mid week, we are going to migrate the questions from "Machine Learning" to the Cross Validated site. Some will be closed as off topic, but for the most part, they would love to see your Machine Language questions there. Make Machine Learning a strong subject on the Cross Validated site by asking your questions there.

For the smaller group of questions that do not fit on that site, support the Computer Science proposal. Bring your questions to these sites and make your presence known in the tags you care about. There is no purpose in continuing a sub-site like this when the subject is well-covered elsewhere.

A larger, more comprehensive site is a win-win to everyone.

Thank you for the link Dov. I almost forgot I put it up there. What do you take from that post? –  Tal Galili Feb 21 '12 at 21:03
@TalGalili. I think that I'm the one that need to say "thank you for this post"... :) though at that time, you thought that there is sort of "battle" between the sites. SE become more statistically oriented where MO become a machine learning oriented. Hence, I think that although those fields are sometime overlap and each community can learn from each other, I think that ML could benefit from a site for its own. Theoretically, I wish to see it here at SE – as the setup here is more convenient. (Until this will happen, I think that will be mostly at MO). - Excuse me for my Israeli accent :) –  Dov Feb 23 '12 at 22:25

For informational purposes, the list of questions that were migrated were:

Seems like none of them got the tag [machine-learning]? –  tdc Feb 23 '12 at 9:54

Tried to go through and edit the tags on my own questions but quickly got:

Too many edits

You have already edited 5 of your own posts today (not including very recent posts). Further edits are not allowed until tomorrow.

Please contact a moderator if you require assistance.

Yeah, the system thinks you are self-vandalizing -- unfortunately I can't remove the blockade manually. We (mods) are working to fix untagged questions -- lack of machine-learning tag is not a big problem because many of the CV's original ML questions were missing this tag. –  mbq Feb 23 '12 at 10:31
@mbq not just machine-learning tag - any tags that were used on ML.SE but didn't exist on stats.SE got lost on the way over, so some Q's have no tags at all –  tdc Feb 23 '12 at 16:39
Precisely -- you can check that there are no more untagged posts from ML, we are working to adjust the rest. –  mbq Feb 23 '12 at 18:11
Ok gone through them all. –  tdc Feb 24 '12 at 9:27
