Building embeddings from abstraction-neuron activations: less spelling noise, stabler vector math

mayfer · x · 2026-10-23

Inspired by @nickcammarata's "already clean" essay, the author built an embedding engine that composes vectors from common abstraction neuron activations instead of raw text encoding. Tested on the top 10k English words, it behaves more consistently in embedding math, is less distracted by spelling/formatting, and focuses on the abstractions present. It's not always better but is generally on par, and it hasn't broken down into returning junk.
