Rainfall Spatial Interpolation with?Graph Neural Networksractical rainfall interpolation well. To address these limitations, we propose a novel GSI (.raph for .patial .nterpolation) model, which focuses on learning the spatial message-passing mechanism. By constraining the message passing flow and adaptive graph structure learning, GSI can perform effecti

Adversarial Learning-Based Stance Classifier for?COVID-19-Related Health Policiesorporate policy descriptions as external knowledge into the model. Meanwhile, a GeoEncoder is designed which encourages the model to capture unobserved background factors specified by each region and then represent them as non-text information. We evaluate the performance of a broad range of baselin

To enhance the stability and learning ability of contrastive learning-based fine-tuning, we design the data augmentation mechanism and type-aware networks to enrich the instances and stand out the class-sensitive features.
