• 11:0311:03, 12 October 2024 diff hist 0 POVM →Definition: after my previous edit it makes sense to reorder the paragraphs, so that the first few are talking about the general measure theoretic definition and the rest are only about the discrete case.
• 11:0111:01, 12 October 2024 diff hist +114 POVM →Definition: there is some confusion on the talk page - I think the issue might be that the article kind of mixes up the general measure theoretic case with the discrete case, and also tries to mix in an informal "naive" approach based on density functions. It's a bit of a mess and this edit at least tries to separate out the measure theoretic definition from the description of the discrete case.

• 09:5409:54, 26 June 2024 diff hist −94 Ordered vector space →Positive cones and their equivalence to orderings: pointed already means it contains 0, so there's no need to keep saying "with vertex 0" all the time as well.

• 04:2904:29, 7 December 2023 diff hist +6 De Finetti's theorem →Statement of the theorem: it's important for de Finetti's theorem that we consider all probability measures over [0,1] and not (for example) finitely supported distributions or distributions that can be represented by probability density functions. The word "distribution" suggests one or other of these things, so I changed it to "measure", which is the technically correct term.

• 07:4707:47, 11 April 2022 diff hist +20 Free energy principle to say it is formal is really not correct - the theory is clearly a work in progress and the precise statement, if there even is one, seems to change from one paper to the next.
