models of mind · rebuilt from the paper · running in this tab
Cognitive science publishes a great many models and very few you can actually poke. The code, when there is code, is a notebook in a footnote that stopped running three library versions ago. This wing takes models worth playing with, reimplements them from the paper in Rust, compiles them to WebAssembly, and puts them behind a URL — with the replication against the published result shown on the page, so you can see for yourself whether the rebuild earns the citation.
Falandays, Nguyen & Spivey (2021) · Brain Research 1768:147578
A hundred randomly wired spiking neurons, each doing nothing but holding its own activation near a private target. No teaching signal, no stored sequence, nothing anywhere that represents a prediction. Train it on toy sentences, cut the input off, and its fading activity rolls into the pattern for the word that would most likely have come next — with the strength tracking how often it actually did. An argument that prediction in brains might be much cheaper than the Bayesian story needs it to be.
