PCA exposes striking geometry inside a protein language model
burny_tech · x · 2026-07-24
A research thread looks at protein language model interpretability through PCA, showing striking geometry inside embeddings and asking the harder question: does the model actually use that structure?
It uses Silico’s built-in interpretability tools on ESMC-6B to inspect representations of protein folds such as a beta-propeller fold, highlighting that visually elegant latent structure does not automatically imply mechanistic relevance.
