I was going to answer a question about reinforcement learning and wanted to show some formulas using the same notation I use on CrossValidated, for instance:

$r_{t+1}+\gamma \max_a Q(s_{t+1},a)$

But it is currently not supported, at least the way I tried it. Can we have support for LaTeX formatting here?

Examples:

Yes, absolutely. Regardless of your position on the whole "theory vs. implementation" thing, math is an essential part of AI and having convenient access to LaTex would be a boon here.

Here are $22$ questions/answers which would benefit from a MathJax support on this website:

These are just a few examples I've found in a 5 minutes search on this website. Nevertheless, I think this number is enough to justify a MathJax support on this website.

I think we should discourage the use of LaTeX, but should allow it. Our goal is to attract experts in AI, and the language of AI (today) is math. Like that post in the OP (which I wrote, btw), I think math makes a lot of concepts easier to understand.

I think this SE should focus on the design aspects of AI and AI research instead of the programming and libraries (those questions should go to Data Science) or the statistics (those should go to Cross Validated), but some mathematics is often a core component of AI theory.

While it might be nice to have for some questions, most questions you would need LaTeX for should be off-topic here. This site is not meant for machine learning questions, as Cross Validated and Data Science Stack Exchange sufficiently cover those subjects.

See: Are all questions asked on stats and data science SE also on topic here?

Note: I posted this answer when I didn't know very much about AI, and I have misunderstood or missed some of the parts of AI that should be on-topic here, I am now of the opinion that we should have LaTeX here. I'll leave this answer here because of the votes (and vote balance) on it, but I don't agree myself anymore with it. So please count an extra downvote from me.

    $\begingroup$ I disagree @wizzwizz4 . We want to attract experts in AI, and experts in AI speak math. While the questions here might be different from those in crossvalidated and datascience, the audience is expected to have a big overlap $\endgroup$ – Harsh Aug 4 '16 at 18:21

    $\begingroup$ "While it might be nice to have for some questions, most questions you would need LaTeX for should be off-topic here." -- that's just not true. It is not the case that you only need math if you're talking about machine learning. Math is the language of science in general. If we want to talk real, serious science here, we should have MathJax here. $\endgroup$ – mindcrime Aug 18 '16 at 15:35

I, for one, would love its inclusion. I do not believe it is possible to divorce AI from mathematics on many levels. For instance, I wanted to ask a question regarding the use of backpropagation with regards to the ANFIS model but had to do so in a clumsy way as I was not able to include the proper notation for partial derivatives. It would surprise me to think that this site is just for "high level" philosophical discussions on AI.

I would like to add to the calls for LaTeX support with a specific topic.

In my opinion, the AI Stack Exchange should be the home for questions about Reinforcement Learning.

RL questions actually appear in larger numbers on Data Science and Cross Validated Stack Exchange sites. That makes little sense to me, when AI, robotics and other better homes in a conceptual sense exist for this topic.

RL is a technical subject requiring solid understanding of underlying maths, especially for anyone wanting to engage in algorithm design. I would like to be able to write equations and maths-based pseudo code when writing questions or answers about RL. It is a shame that this site presents a barrier to doing that. Along with the larger audience for other Stack Exchange sites, this one is losing out IMO on a current hot topic that could provide much traffic. And in part that is due to barriers when writing content.

Starting a new list of math questions to expand on nbro's list:

$\endgroup$

    $\begingroup$ can add ai.stackexchange.com/q/6308/1641 to the list. The question would be a lot more clear if the Equation that it's about could be comfortably written in the question, rather than requiring people to download the linked paper and find the Equation. My answer to the question would also be much more readable with proper MathJax over... whatever I ended up doing. $\endgroup$ – Dennis Soemers Aug 7 '18 at 13:13
  • $\begingroup$ @DennisSoemers Added. (Feel free to directly update this list. Nbro's list original list, I think, is static at this point, so I created this one as a supplement.) $\endgroup$ – DukeZhou Aug 7 '18 at 19:19
