P$^2$C$^2$Net: PDE-Preserved Coarse Correction Network for efficient prediction of spatiotemporal dynamics

NeurIPS 2024poster

When solving partial differential equations (PDEs), classical numerical methods often require fine mesh grids and small time stepping to meet stability, consistency, and convergence conditions, leading to high computational cost. Recently, machine learning has been increasingly utilized to solve PDE…

Unifying Predictions of Deterministic and Stochastic Physics in Mesh-reduced Space with Sequential Flow Generative Model

NeurIPS 2023spotlight

Accurate prediction of dynamical systems in unstructured meshes has recently shown successes in scientific simulations. Many dynamical systems have a nonnegligible level of stochasticity introduced by various factors (e.g. chaoticity), so there is a need for a unified framework that captures both de…

Bayesian Spline Learning for Equation Discovery of Nonlinear Dynamics with Quantified Uncertainty

NeurIPS 2022accept

Nonlinear dynamics are ubiquitous in science and engineering applications, but the physics of most complex systems is far from being fully understood. Discovering interpretable governing equations from measurement data can help us understand and predict the behavior of complex dynamic systems. Altho…

Predicting Physics in Mesh-reduced Space with Temporal Attention

ICLR 2022poster

Auto-regressive sequence models for physics prediction are often restricted to low-dimensional systems, as memory cost increases with both spatial extents and sequence length. On the other hand, graph-based next-step prediction models have recently been very successful in modeling complex high-dimen…
