Martin Pál's question on the Warren Buffett problem is currently tagged with gt.game-theory, machine-learning and online-learning. Should the gt.game-theory tag instead be lg.learning-theory ? See also this related discussion on machine-learning vs learning-theory.

  • $\begingroup$ IMHO, it would be nice if all learning questions have the lg.learning-theory tag, but I am not sure if we need to remove the gt.game-theory tag. $\endgroup$

  • $\begingroup$ I think @Suresh means machine-learning to lg.learning-theory, no? But the lg.learning / machine-learning / learning-theory, etc. tags are a complete mess... $\endgroup$

  • $\begingroup$ @Suresh: It seems like a question about effective Hausdorff dimension to me, instead of either of those. Not-necessarily-fair reward functions that are oblivious to the past, and the user starts with a finite initial budget and tries to maximize profit. This sounds a lot like gales and martingales, in which case there is a lot of literature. I haven't posted there yet because I was away, and I don't know if I'm reading it right. $\endgroup$ Oct 23 '10 at 22:35
  • $\begingroup$ I have no opinion about [machine-learning] vs [learning-theory], but why is the proposal of adding the [learning-theory] tag to the question coupled with the removal of the [gt.game-theory] tag? $\endgroup$ Oct 23 '10 at 22:37
  • $\begingroup$ because I don't think game-theory is a relevant tag for this question $\endgroup$ Oct 23 '10 at 23:54

    $\begingroup$ (Reposting a comment with a minor edit because my previous comment disappeared during the datacenter relocation.) I have no opinion about whether this question is related to game theory or not, either, but addition of [lg.learning-theory] to this question and removal of [gt.game-theory] are two different things which should not be coupled in decision making. In other words, this is not a retag request. $\endgroup$ Oct 24 '10 at 11:26

sorry, I'm new here. I agree the game-theory is not an appropriate tag and I've removed it. I've added lg.learning (lg.learning-theory doesn't seem to be an existing tag).

I think this question should not be tagged gt.game-theory but instead as Suresh suggests, lg.learning-theory is the right tag here.

(I don't think Suresh intended to suggest merging gt.game-theory into lg.learning-theory, although the question could be read that way.)

  • $\begingroup$ that's correct. sorry for the terse comments - have been busy at FOCS. $\endgroup$ Oct 25 '10 at 7:38
