Cool. Classical billiards can compute - but only "for some value of billiard table" I think.

Classical billiards can compute
We show that two-dimensional billiard systems are Turing complete by encoding their dynamics within the framework of Topological Kleene Field Theory. Billiards serve as idealized models of particle mo...

Why does anyone use the Wilcoxon test for anything?
It's not even transitive. It's sensitive to things one most likely is not looking for (changes in distribution shape) and relatively insensitive to what one usually is looking for (change in location).

Am contributing to a collaborative dry-wet project proposal and everyone incl. myself thinks I should be writing about fancy algorithms. Instead, I spend all time on experimental design,power, what do we know or not, what do we aim to show? And on 2nd thought, that's probably OK for a statistician.

So often there’s a gulf between knowing (a particular aspect of) a topic and understanding it from multiple perspectives. Like the analogy here to matrices vs linear algebra.
“Everyone knows” what an autoencoder is… but there's an important complementary picture missing from most introductory material.
In short: we emphasize how autoencoders are implemented—but not always what they represent (and some of the implications of that representation).🧵

We didn't randomize, and there was no allocation concealment or blinding, and we can't really be sure what intervention they got or how the outcomes were measured, but we emulated a trial by drawing a DAG.
