HAMNO: A Hierarchical Adaptive Multi-scale Neural Operator with Physics-Informed Learning for Dynamical Systems
Researchers have introduced HAMNO, a novel neural operator architecture designed to better handle complex dynamical systems. HAMNO combines local convolutional and global spectral operators with a hierarchical structure and a data-dependent gating mechanism to adaptively balance information. A physics-informed extension, PI-HAMNO, further enhances stability and data efficiency by integrating data fitting with physics constraints. AI
