Researchers have developed a new method called Adaptive Probability Flow Residual Minimization (A-PFRM) to address the challenges of solving high-dimensional Fokker-Planck equations. This approach reformulates the problem as a first-order continuity equation, enabling neural network approximations without requiring Hessian computations. The method incorporates the Hutchinson trace estimator for dimension-independent divergence calculations on GPUs and employs adaptive sampling strategies for collocation points. Numerical experiments demonstrate A-PFRM's effectiveness on various complex problems, including Ornstein-Uhlenbeck processes and Geometric OU processes, up to one hundred dimensions. AI
