| Nov 18, 2015 at 8:49 | comment | added | Dirk | @QiaochuYuan Should your comment say that a boring toy model of Bayesian updating is related to a boring toy model of categories? But wait, inclusion of sets in not really a toy model for categories, so… | |
| Nov 17, 2015 at 21:11 | comment | added | მამუკა ჯიბლაძე | I remember a talk by Alex Simpson on categorical treatment of conditional independence, where some sort of things-over-a-base were essential. He referred to a question here on MO; one of the answers to this question opens with a link to the paper entitled "A Categorical Foundation for Bayesian Probability". I have not seen it but maybe... | |

Here's a toy model of Bayesian updating: your state of knowledge about the world is represented by a subset $S$ of the set $X$ of states the world could be in. Someone tells you a fact about the world; now you've learned that the state of the world lies in a subset $T$. Your new updated state of knowledge is $S \cap T$. Is there an interesting category structure here? Maybe inclusion of subsets, but that's not so interesting. | |
