Researchers have developed a new framework called UG-UMRE to improve unified multimodal relation extraction (UMRE). This approach addresses issues of noise propagation from inherent uncertainty and the heterogeneity between different modal distributions. UG-UMRE incorporates an Uncertainty-Driven Unimodal Augmentation (UDUA) module that models features as Gaussian distributions and uses self-supervised contrastive learning to filter noise. Additionally, a Joint Aleatoric Uncertainty Alignment (JAUA) module pre-calibrates semantics by aligning statistical properties across modalities into a shared latent space. Experiments on benchmark datasets show that UG-UMRE achieves state-of-the-art performance. AI
