Manifold-Orthogonal Dual-spectrum Extrapolation for Parameterized Physics-Informed Neural Networks
Researchers have introduced Manifold-Orthogonal Dual-spectrum Extrapolation (MODE), a novel micro-architecture for adapting physics-informed neural networks (PINNs). MODE addresses limitations in existing methods like SVD-based fine-tuning and conventional parameter-efficient fine-tuning (PEFT) by decomposing physical evolution into distinct mechanisms. This approach enables cross-modal energy transfer, activates high-frequency spectral components, and isolates spatial translation dynamics, achieving strong out-of-distribution generalization with minimal parameter complexity.
