New method distills nonlinear dynamics into linear state-space models

Researchers have developed a novel pipeline for learning linear state-space models from nonlinear dynamical systems. This method, termed Spectral Distillation, uses Observation Spectral Filtering (OSF) to first learn an implicit spectral predictor through a convex approach. Subsequently, this predictor is converted into an explicit recurrent linear dynamical system. The approach offers a provable guarantee on prediction error, dependent on observer complexity rather than latent dimension, and has demonstrated effectiveness in experiments on both linear benchmarks and MuJoCo behavior cloning.

    Spectral Distillation: From Nonlinear Dynamics to Linear State-Space Models

    arXiv:2608.05416v1 Announce Type: new Abstract: Can nonlinear dynamical systems be learned through a compact linear state-space representation, without directly solving a non-convex system-identification problem? We give a provable pipeline for doing so. Starting from observation…
