Yuhan Chen, Takashi Matsubara, Takaharu Yaguchi
A theoretical framework combines Kolmogorov–Arnold–Moser (KAM) theory with statistical learning theory to analyze Hamiltonian Neural Networks (HNNs), demonstrating the preservation of quasi-periodic dynamics despite non-zero training loss. The work also proposes an HNN extension that learns canonical coordinate transformations, broadening applicability to real-world data.
Key insights
- Small, non-zero learning errors in HNNs, when bounded globally, can still allow for the preservation of quasi-periodic dynamics, as predicted by KAM theory.
- Statistical learning theory offers the tools to establish the global L-infinity error bounds on learned Hamiltonians required to apply classical stability theorems to neural network models.
- HNNs can be designed to intrinsically learn optimal coordinate transformations, making them adaptable to observed data not initially in canonical phase space coordinates.
