Studies answer-conditioned P(True) and trains a separate P(IK) value head from sampled correctness labels to estimate answerability before selecting a particular answer.
Scientific scope
Studies answer-conditioned P(True) and trains a separate P(IK) value head from sampled correctness labels to estimate answerability before selecting a particular answer. Source-reported calibration and partial cross-task generalization, not access to ground truth or guaranteed honesty. P(IK) finetunes the whole model plus head; out-of-distribution calibration remains weak. Stars mark correspondence, not equal contribution.
Evidence
The linked original sources describe the stated contribution and its evidence limits. WRS has not independently rerun the experiments or certified a proof. Source-reported calibration and partial cross-task generalization, not access to ground truth or guaranteed honesty. P(IK) finetunes the whole model plus head; out-of-distribution calibration remains weak. Stars mark correspondence, not equal contribution.
