Paper: ATTNPO: Attention-Guided Process Supervision for Efficient Reasoning

What they're saying

Identifies "special attention heads that naturally focus on essential steps while suppressing redundant ones."...

The Critique

Assumes attention scores indicate which steps are essential (attention ≠ explanation). No mechanistic validation. Circular: redundant steps are those with low attention, low attention indicates redundancy.

Why It Matters

If field adopts attention-based process rewards based on correlational evidence, risk building systems that optimize for proxy signals rather than actual reasoning quality.

What They Missed

Assumes attention scores indicate which steps are essential (attention ≠ explanation). No mechanistic validation. Circular: redundant steps are those with low attention, low attention indicates redundancy.
