- Reposted by Moritz Schauerwikipedia turns 25 today! the last unenshittified major website! backbone of online info! triumph of humanity! powered by urge of unpaid randos to correct each other! somehow mostly reliable! "good thing wikipedia works in practice, because it sure doesn't work in theory" - old wiki adage
- At a technical university the steps of Pearl’s ladder are called stochastics, stochastic control and optimal transport
- Causal inference is often hidden in plain sight. In a randomized clinical trial, the setup is such that interventional and conditional distributions coincide. That is E(X | do(T = t)) = E(X | T = t).
- In classical approaches, correctness of causal claims is argued at the meta level, by appealing to design or understanding. In the do-calculus, that burden is shifted into a mathematical formalism.
- REMEMBERING HARRY VAN ZANTEN Botond Szabó and Aad van der Vaart in the ISBA Bulletin.
- Students learn early that correlation does not imply causation. Correct, but incomplete... Certain patterns of independence and conditional dependence constrain #causal structure very strongly. A simple example:
- So consider two variables: sunlight exposure and estrogen level. A priori, it is not obvious that either is related to bone mineral density. Empirically, in the population, sunlight exposure and estrogen level are independent*. No causal assumptions are made beyond that.
- Now restrict attention to individuals with low bone mineral density. Within this group, sunlight exposure and estrogen level are no longer independent. If one is normal, the other is more likely to be deficient. Conditioning has created dependence.

- Vaguely funny expression: a serious title
- God made not only the numbers but also a sequence of independent standard normal random variables.
- The (samizdat?) solution book to the classic soviet era “Problems In Mathematical Analysis” by Demidovich was called “Anti-Demidovich” by the students. 😀
- The event B having happened is not the same as the receiving the information O that the event B has happened, because you also condition on receiving the information at all in the latter case. Conflating this contributes a lot to the "paradoxa" such as boy/girl paradox, Monty Hall...

- Reposted by Moritz SchauerOur process causation paper is published in Synthese! We propose that process causation (a la Salmon, Dowe, MDC new mechanists) can be modeled using a category-theoretic framework. link.springer.com/article/10.1...
- Confounding is just the failure of the Doob conditioning functor from a Markov category into the associated category of backward-forward optics to be lax comonoidal
- Oh, hats up to Mike Hicks who authored a policy paragraph on double-blind reviewing and amphibious type systems for POPL 2013 which has stand the test of time and is used in ICSME, OOPSLA, ECOOP, SPLASH, ICFP, PLDI, POPL, CSF, CAV... pldi12.cs.purdue.edu/others/dbr-f...

- It’s giving late-game vibes of Sid Meier’s Civilization, where the player is bored and just trying to see what happens if they declare some wars before they abandon the game.
- Reposted by Moritz SchauerHas nominative determinism gone too far h/t @benjaminschneider.ch
- Right, you don't need error bars on error bars. Probabilistic uncertainty about uncertainty collapses. This is the “monadic join” in probability. Instead of a coin with random bias p ∼ π, you can flip a coin with the deterministic bias μ. Just take μ = E[p]. #statistics
