Calibration vs Decision Making: Revisiting the Reliability Paradox in Unlearned Language Models
arXiv:2605.20915v1 Announce Type: cross Abstract: Machine unlearning aims to remove the influence of specific training data from a model while preserving reliable behavior on the remaining data, making reliable prediction and uncertainty estimation essential for evaluation. Calibration is commonly used as a proxy for reliability in language models, but low calibration error does not necessarily imply reliable decision rules, as models may rely on spurious correlations while remaining well calibrated. We investigate this gap in generative language models using the multiple-choice question-answe
The increasing focus on reliable and interpretable AI systems, especially within generative language models, makes the understanding of unlearning effects on calibration critical now.
Reliability and calibration are crucial for the safe and ethical deployment of large language models, particularly in sensitive applications where unlearning is required for data privacy or compliance.
This research highlights that low calibration error does not guarantee reliable decision-making in unlearned models, potentially requiring new evaluation metrics beyond traditional calibration.
