Calibrating LLM Judges: Linear Probes for Fast and Reliable Uncertainty Estimation (2026.acl-industry)

Copied to clipboard

Challenge: Existing methods for obtaining well-calibrated uncertainty estimates are poorly calibrated or computationally expensive.
Approach: They propose a linear probe that provides calibrated uncertainty estimates from reasoning judges’ hidden states, requiring no additional model training.
Outcome: The proposed method achieves superior calibration compared to existing methods with x computational savings, generalizes robustly to unseen evaluation domains, and delivers higher accuracy on high-confidence predictions.
