Physics-based active learning boosts neural operator training efficiency

Researchers have developed a new active learning technique called physics-based acquisition to improve the efficiency of training neural operators. This method uses the partial differential equation residual to intelligently select the most informative data samples for training. Experiments on the 1D Burgers and 2D Navier-Stokes equations demonstrate that this approach significantly reduces data requirements compared to random sampling and matches state-of-the-art data efficiency while incorporating physics into the model's understanding.
