TinyUDE: Solver-Free Universal Differential Equations on Microcontrollers via Lie-Taylor Jet Matching

TinyUDE introduces a solver‑free training framework for Universal Differential Equations (UDEs) that fits a hybrid vector field directly to the first and second time‑derivatives of observed system states using Lie‑Taylor jet matching. The method estimates these derivatives online via Savitzky‑Golay filtering, enabling fully analytic gradients without automatic differentiation. Experiments on damped and chaotic pendulum systems show that TinyUDE matches or surpasses conventional solver‑based baselines while using less than 108 kB of static memory and achieving real‑time on‑device training on an ESP32 microcontroller.
