Knowledge graph (KG) embeddings have shown great power in learning representations of entities and relations for link prediction tasks. Previous work usually embeds KGs into a single geometric space such as Euclidean (zero curved), hyperbolic (negatively curved) or hyperspherical (positively to maintain their specific structures (e.g., chain, hierarchy ring structures). However, the topological structure appears be complicated, since it may contain multiple types simultaneously. Therefore,...

Introduction China has the largest population of diabetic patients (about 116 million) in world. As a novel model fat index for Chinese people, visceral adiposity (CVAI) was considered reliable indicator to assess dysfunction fat. This study aimed explore dose–response relationship between CVAI and type 2 diabetes mellitus (T2DM) population, considering as continuous/categorical variable. Method Baseline follow-up data were collected from waves 2011 2015, respectively, Health Retirement...

Real-world datasets often exhibit a long-tailed distribution, where vast majority of classes known as tail have only few samples. Traditional methods tend to overfit on these classes. Recently, new approach called Imbalanced SAM (ImbSAM) is proposed leverage the generalization benefits Sharpness-Aware Minimization (SAM) for distributions. The main strategy merely enhance smoothness loss function However, we argue that improving in long-tail scenarios requires careful balance between head and...
