arXiv:2606.05371v1 Announce Type: new Abstract: Reduced-order modeling of high-dimensional dynamical systems is often hindered by the non-Markovian closure term that represents the effect of unresolved variables on the resolved dynamics. Inspired by the Mori--Zwanzig formalism, in which the closure takes the form of a memory functional of the resolved trajectory, we recast closure modeling as a sequence modeling problem and propose the Mamba-Assisted Closure (MAC) framework: a Mamba-based sequence model, trained to predict the closure from the resolved trajectory, is coupled with the reduced-o
This development leverages recent advancements in sequence modeling (Mamba architecture) to address a long-standing challenge in high-dimensional system reduction, indicating ongoing progress in AI's application to scientific computing.
Improved reduced-order modeling can significantly accelerate scientific discovery, engineering design, and operational forecasting in complex systems by making simulations more efficient and accurate.
The explicit coupling of advanced AI sequence models with reduced-order modeling techniques offers a new pathway to overcome the 'non-Markovian closure' problem, potentially making complex system simulations more tractable and less computationally intensive.
