arXiv:2605.25826v1 Announce Type: cross Abstract: We develop a branched signature kernel solver for linear and nonlinear ordinary differential equations driven by a \emph{single observed trajectory} of a possibly rough forcing signal -- a setting that arises naturally in earthquake engineering, finance, biology, and structural health monitoring, where the forcing is observed exactly once and the solver must respect the underlying physical law without recourse to an ensemble of realizations. Two ingredients are new. First, a \emph{count-sampling} construction turns the single observation into a
This research provides a novel computational approach leveraging advanced mathematical concepts in AI to solve complex differential equations that are critical in various scientific and engineering domains.
The Branched Signature Kernel Solver improves the capability of AI models to interpret and predict behavior from rough, single-trajectory data, expanding AI's applicability in fields like earthquake engineering and structural health monitoring.
Traditional ODE solvers often require ensemble data or encounter difficulties with rough, single-trajectory signals; this new method offers a more robust solution for such challenging real-world scenarios.
