Predictive entropy from one model pass predicts both calibration failures and paraphrase sensitivity in medical VLMs, enabling a single threshold to identify problematic outputs.
First, LoRA fine- tuning is the primary calibration mechanism; no post-hoc UQ method applied to the base model comes close
