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.

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.

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.
