Anthropic paper reframes double descent as a phase transition from memorization to structure

Aleksa Gordic highlights Anthropic's Transformer Circuits paper 'Superposition, Memorization, and Double Descent': double descent can be read as a phase transition between memorizing individual examples (datapoints encoded as distinct directions in hidden space) and learning reusable structure — a mechanistic take on why overfitting matters for interpretability.
