New method improves multi-modal regression reliability with missing data

Researchers have developed a new method called modality-aware conformal calibration to improve the reliability of multi-modal regression models, particularly when dealing with missing or conflicting data sources. This approach uses a calibration layer that trains separate predictors for each modality and calculates a disagreement score. This score is then used to adjust prediction intervals, either by reallocating width across examples or by stratifying predictions within groups defined by modality availability. Experiments on four datasets showed that this method matches or improves upon existing baselines for prediction interval accuracy and width, while also recovering significant coverage in scenarios with missing modalities.
