arXiv:2605.08390v2 Announce Type: replace Abstract: Sequence prediction methods for linear dynamical systems with long memory, i.e. marginally stable systems, typically achieve regret that grows linearly with the hidden dimension of the underlying generative model. While many methods have been developed to address this regime with varying success, we show that simply using the second-order Vovk-Azoury-Warmuth (VAW) algorithm to learn a short autoregressive-with-inputs (ARX) model achieves astoundingly strong results: for bounded sequential data from a marginally-stable linear dynamical system
Ongoing research in AI and machine learning continually seeks more efficient and accurate predictive models, making advancements in sequence prediction methods a current focus.
Improved sequence prediction, especially for systems with long memory, can significantly enhance the performance and reliability of AI agents and automated systems operating in complex, dynamic environments.
Traditional challenges in predicting outcomes in marginally stable linear dynamical systems may be overcome with simpler, yet more powerful, second-order methods, potentially accelerating AI development.
