Enhancing the Inductive Biases of Graph Neural ODE for Modeling Physical Systems

ICLR 2023poster

Neural networks with physics-based inductive biases such as Lagrangian neural networks (LNNs), and Hamiltonian neural networks (HNNs) learn the dynamics of physical systems by encoding strong inductive biases. Alternatively, Neural ODEs with appropriate inductive biases have also been shown to give…

Learning Articulated Rigid Body Dynamics with Lagrangian Graph Neural Network

NeurIPS 2022accept

Lagrangian and Hamiltonian neural networks LNN and HNNs, respectively) encode strong inductive biases that allow them to outperform other models of physical systems significantly. However, these models have, thus far, mostly been limited to simple systems such as pendulums and springs or a single r…

Unravelling the Performance of Physics-informed Graph Neural Networks for Dynamical Systems

NeurIPS 2022accept

Recently, graph neural networks have been gaining a lot of attention to simulate dynamical systems due to their inductive nature leading to zero-shot generalizability. Similarly, physics-informed inductive biases in deep-learning frameworks have been shown to give superior performance in learning th…
