Calibrated Uncertainty Estimation for LLM Clinical Text Classification

A new arXiv paper addresses the risk of overconfident errors when large language models classify clinical text, where a wrong label can affect patient care. The authors note that current black-box approaches simply attach a confidence score to an unchanged LLM prediction, and they propose an uncertainty-aware method designed to produce better-calibrated results. The work targets medical NLP settings where knowing when a model is unreliable matters as much as the predicted label itself.

arXiv Paper Proposes Human-Grounded Calibration for Long-Text Image-Text Matching

A new arXiv preprint addresses the difficulty of judging whether lengthy descriptive text actually matches an image, a task relevant to vision-language systems. The authors note that raw similarity scores from dual-encoder models are hard to interpret and propose calibrating them against human judgments. The work targets more reliable long-text image-text congruence scoring.

Paper Argues LLM-Judge Calibration in Biomedical ML Needs Four Separate Ledgers

A new arXiv paper examines how synthetic perturbations are often used as cheap calibration data for LLM evaluators in biomedical machine learning, where expert review is limited. The authors argue that a planted mutation key should not be treated as either a detector output or automatically as human ground truth. They propose formalizing four distinct ledgers to make reporting of calibration results more responsible.

Calibration Audit Questions Confidence Scores in Feed-Forward 3D Reconstruction Models

A study examines whether the per-pixel confidence values produced by feed-forward 3D reconstruction models can be treated as reliable uncertainty estimates. Because these scores are trained mainly as loss weights, the authors audit how well they are calibrated for downstream use. The paper reports on the limits of reusing them as an uncertainty signal.

Reliability-Aware Hybrid-K Ensemble Selection Proposed for Cervical Cytology Classification

A new arXiv preprint introduces a hybrid ensemble selection framework for multiclass cervical cytology image classification that weighs discriminative performance alongside calibration and selective prediction. The authors argue that raw accuracy is not enough for clinical image analysis, and that the method is meant to deliver trustworthy confidence scores and uncertainty flags so users know when to distrust a prediction. The work appears in the cs.AI category as an early-stage research contribution.
