Show HN: A Neural Network Implemented Entirely in SQL

GitHub / Hacker News·low signal

A Show HN (105 points) implements a working MNIST neural network purely in SQL, running training and inference as queries in an xarray-sql demo. It's a technical curiosity that also stress-tests how far declarative query engines can be pushed toward ML primitives. Interesting reference for the 'databases as compute substrate' thread that keeps recurring in agent and analytics tooling.
