Coarse Graining with Neural Operators for Simulating Chaotic Systems
Overview
Paper Summary
This paper proposes a machine-learning framework for predicting the long-term behavior of chaotic systems, focusing on fluid dynamics. By learning a simplified version of the system's evolution, the method achieves significant speedups compared to traditional simulations while maintaining good accuracy in predicting statistical properties. The method utilizes a multi-fidelity training approach to minimize the need for computationally expensive, fully-resolved simulations.
