Researchers have developed PRA-PoE, a novel multimodal learning framework designed to improve Alzheimer's disease diagnosis, even when data from some modalities is missing. This framework addresses the challenge of varying missingness patterns in real-world clinical assessments by explicitly modeling modality availability and uncertainty. PRA-PoE utilizes Prototype-anchored Representation Alignment to reduce representational shifts and an Uncertainty-aware Product of Experts for robust fusion, outperforming existing methods on key datasets.
