Researchers have introduced Time-varying Interaction Graph Ordinary Differential Equations (TI-ODE), a novel method for dynamic graph representation learning. This approach addresses limitations in existing models by decomposing the evolution function into learnable interaction basis functions that dynamically combine over time. TI-ODE aims to capture the diverse and time-varying nature of inter-node interactions more effectively. Experiments on multiple datasets, including one related to Covid, show TI-ODE achieving state-of-the-art performance and demonstrating superior robustness compared to previous methods. AI
