Recovering Physical Dynamics from Discrete Observations via Intrinsic Differential Consistency

Researchers present a novel method for reconstructing continuous-time physical dynamics from discrete observations by enforcing the semi-group property of autonomous flows, using a metric called Symmetry Rupture to regularize training and guide adaptive step selection. The approach significantly outperforms Neural ODE baselines on diffusion-reaction and PDE benchmarks, reducing errors by 87% while requiring 5x fewer function evaluations.

Discovering Ordinary Differential Equations with LLM-Based Qualitative and Quantitative Evaluation

Researchers introduce DoLQ, a new method that combines large language models with symbolic regression to discover ordinary differential equations from observational data. The approach integrates both qualitative physical reasoning and quantitative metrics through a multi-agent architecture, demonstrating superior performance over existing methods in recovering accurate symbolic equations.

Geometric Kolmogorov--Arnold Network (GeoKAN)

Researchers introduce Geometric Kolmogorov-Arnold Networks (GeoKANs), an advancement in KAN-type neural networks that learn geometry-adapted coordinate systems rather than relying on fixed Euclidean inputs. By adapting a diagonal Riemannian metric during training, GeoKAN redistributes computational capacity toward regions of rapid variation, making it particularly effective for physics-informed learning and differential equation problems.
