If I had been planning better I wouldn't have put a bounty on this question that expires during a week when I'm extremely busy. But it looks promising and I hope to have a chance to work through it at the proper pace sometime later. A high-level tl;dr as an answer below would be greatly appreciated! | |
| Jun 5, 2020 at 15:49 | comment | added | πr8 | speculatively: i would guess that computing the partition function is often singled out as "the" hard task because it somehow requires the least extra detail to be explained - you don't need to be looking for a specific { marginal / conditional } distribution, or for the integral of a specific function; it's 'just' a normalising constant, which 'just exists' without extra detail. | |
| Jun 5, 2020 at 15:44 | comment | added | πr8 | in your final comment, (a) and (b) are in a sense quite unrelated. at a high level, (a) is about optimisation, and (b) is about integration. roughly speaking, being able to compute partition functions should be useful for integration tasks (computing expectations, marginals, conditional distributions, sampling). see section 1.5 of web.stanford.edu/~montanar/TEACHING/Stat375/handouts/… for details on how these reduce to one another. | |
