The paper proposes a novel approach called Causal Graph Ordinary Differential Equations (CAG-ODE) for modeling dynamic multi-agent systems, such as the spread of COVID-19 in the US. This approach captures the continuous interactions among agents using a Graph Neural Network (GNN) and incorporates time-dependent representations of treatments to predict potential outcomes. The model also addresses confounding bias by employing domain adversarial learning-based objectives. CAG-ODE is evaluated on two datasets, demonstrating superior performance compared to existing methods.

The paper develops a new way to understand how different things interact with each other over time. Imagine the spread of COVID-19 as a game where states are players and people moving between them are moves. The goal is to predict what would happen if we made different choices, like telling people to stay at home or get vaccinated. Currently, there’s no good way to do this because it’s hard to account for how these choices affect each other. The new approach, called CAG-ODE, uses a special kind of computer program that can learn from examples and make predictions. It’s tested on two different scenarios, one about COVID-19 and the other about tumor growth, and shows promising results.
