Improving Long-Range Interactions in Graph Neural Simulators via Hamiltonian Dynamics

Published in International Conference on Learning Representations (ICLR), 2026

We propose a novel Graph Neural Simulator that preserves information during propagation, enabling it to model complex physical dynamical systems with long-range dependencies.

ComPhy: Composing Physical Models with end-to-end Alignment

Published in International Conference on Learning Representations (ICLR), 2026

We introduce ComPhy, a multi-module approach to learn systems of PDEs by assigning one equation to each module. An alignment mechanism ensures the networks share information to solve the system together.

Learning and Transferring Physical Models Trhough Derivatives

Published in Transactions on Machine Learning Research (TMLR), 2026

We introduce DERL, a supervised approach based on partial derivatives that is able to learn physical systems and to transfer physical knowledge across models.
