New method enables reusable neural solvers for differential equations

Researchers have developed a new method called Linearized Subspace Transfer (LST) that allows neural network solvers for parametric differential equations to be reused across different conditions. This approach leverages the output Jacobian of a single-condition trained model to define a transferable response space. To address the limitations of a single space's coverage, Active Transfer Modeling (ATM) is introduced, which selectively acquires additional response spaces from other single-condition models based on post-transfer residuals. Experiments across six systems demonstrated that ATM significantly reduces error and offline construction costs compared to physics-informed operator baselines, achieving substantial accuracy gains and rapid adaptation times.
