Researchers have developed a novel method for efficiently sampling from invariant measures of stochastic differential equations (SDEs) by combining operator learning with flow methods. This approach trains a neural sampler to map SDE coefficient functions to desired invariant measures, significantly reducing the cost for new instances after an initial training phase. The framework utilizes Lagrangian trajectory sensors and cross-attention mechanisms to handle high-dimensional problems, demonstrating competitive accuracy and substantial speedups over traditional MCMC methods, particularly for SDEs with slow mixing.
