Cover Story: With Seven-League boots, we are marching through the time-wise direction. The authors proposed a deep-learning-based numerical method, the Seven-League scheme, to solve stochastic differential equations (SDEs) by taking large time steps. SDE discretization is built up by means of the polynomial chaos expansion method, on the basis of accurately determined stochastic collocation (SC) points. By employing an artificial neural network to learn these SC points, we can perform accurate Monte Carlo simulations with large time steps, especially in the sense of strong convergence.
