Researchers have developed CoPoE, a novel framework for multimodal Alzheimer's disease diagnosis that effectively handles missing data. CoPoE maps various types of clinical evidence into a structured latent space representing genetic risk, molecular pathology, neurodegeneration, and clinical stage. By using a Product-of-Experts architecture that only incorporates available modalities, CoPoE avoids synthesizing absent inputs and maintains a robust posterior for any subset of data. Experiments on the ADNI dataset demonstrated CoPoE's superior performance in all-modality and subset evaluations, outperforming existing fusion methods and improving probability calibration metrics.
