🧠A new theoretical framework formalizes when representation properties in supervised learning can be uniquely identified from input-output behavior alone. The research demonstrates that representation-level claims require additional assumptions beyond predictive performance, as auxiliary information can be added to representations while preserving predictor outputs, fundamentally challenging common assumptions about what supervised learning actually determines.
