New FTM method offers fast, accurate predictions for complex systems

Researchers have developed a new surrogate-modeling method called First-Order Trajectory Matching (FTM) designed for predicting chaotic, turbulent, and stochastic systems. FTM learns the local transport of probability mass directly from system trajectories, enabling it to capture essential quantities like fluxes and circulations. This approach avoids complex estimations like drift, diffusion, and score estimation, offering stable and efficient ensemble predictions at a low computational cost. AI
