Researchers have developed a new unsupervised finetuning framework for partial differential equation (PDE) foundation models, eliminating the need for ground-truth solutions. This method utilizes a physics-based objective derived from the PDE residual and boundary conditions, combined with a low-rank adaptation technique called NSLoRA. The approach achieves performance comparable to supervised methods without requiring ground-truth data and outperforms existing neural operator baselines and PDE foundation models on various benchmarks.
