Paper: Features as Rewards: Scalable Supervision for Open-Ended Tasks via Interpretability

What they're saying

Uses sparse autoencoder features as reward signals to train models with 58% less hallucination...

The Critique

Features used as rewards are extracted from same model being trained - circular feedback loop reinforcing existing patterns. No validation that features capture correct answers vs merely confident ones.

Why It Matters

If features encode existing biases, method systematically reinforces confident-but-wrong behaviors in ways undetectable by standard evaluation.

What They Missed

Features used as rewards are extracted from same model being trained - circular feedback loop reinforcing existing patterns. No validation that features capture correct answers vs merely confident ones.
