An Invariant Compiler for Neural ODEs in AI-Accelerated Scientific Simulation

arXiv:2603.23861v1 Announce Type: new Abstract: Neural ODEs are increasingly used as continuous-time models for scientific and sensor data, but unconstrained neural ODEs can drift and violate domain invariants (e.g., conservation laws), yielding physically implausible solutions. In turn, this can compound error in long-horizon prediction and surrogate simulation. Existing solutions typically aim to enforce invariance by soft penalties or other forms of regularization, which can reduce overall error but do not guarantee that trajectories will not leave the constraint manifold. We introduce the invariant compiler, a framework that enforces invariants by construction: it treats invariants as first-class types and uses an LLM-driven compilation workflow to translate a generic neural ODE specification into a structure-preserving architecture whose trajectories remain on the admissible manifold in continuous time (and up to numerical integration error in practice).

It provides a systematic design pattern for invariant-respecting neural surrogates across scientific domains.

Executive Summary

This article presents an invariant compiler for Neural ODEs, a framework that enforces invariants in continuous-time models by construction. By treating invariants as first-class types and utilizing an LLM-driven compilation workflow, the compiler translates a generic neural ODE specification into a structure-preserving architecture. This approach cleanly separates scientific structure from learned dynamics within that structure, providing a systematic design pattern for invariant-respecting neural surrogates. The invariant compiler addresses a critical issue in AI-accelerated scientific simulation, where unconstrained neural ODEs can drift and violate domain invariants, leading to physically implausible solutions and compounded error in long-horizon prediction.
