New Neural Kolmogorov Equations Learn Stochastic Dynamics Efficiently

Researchers have introduced Neural Kolmogorov Equations (NKEs), a novel method for learning stochastic dynamics from data. This approach reformulates Neural Stochastic Differential Equations (SDEs) by focusing on the evolution of probability densities rather than individual trajectories. NKEs can handle general Lévy-type stochastic forcing, including coupled noise and jump processes, and enable parallel-in-time training through Lagrangian Galerkin projection and operator splitting. Evaluations on various benchmarks demonstrate NKEs' ability to accurately model both deterministic and stochastic dynamics with improved training efficiency. AI
