Researchers have developed a new framework for analyzing errors in decoupled neural approximations of fully coupled forward-backward stochastic differential equations (FBSDEs). This method accounts for a control mismatch that arises in practical deep learning implementations, which occurs when the auxiliary control process in the forward coefficients differs from the backward component approximated by the neural network. The framework provides computable a posteriori error bounds based on the terminal defect, pathwise residual, and the control mismatch. Numerical experiments demonstrate the effectiveness of these indicators in ensuring consistency and reproducibility of numerical approximations. AI
