In this paper we propose a generalization of the Deep Galerking Method (DGM) of <cit.> to deal with Path-Dependent Partial Differential Equations (PPDEs). These equations firstly appeared in the seminal work of <cit.>, where the functional Itô calculus was developed to deal with path-dependent financial derivatives contracts. The method, which we call Path-Dependent DGM (PDGM), consists of using a combination of feed-forward and Long Short-Term Memory architectures to model the solution of the PPDE. We then analyze several numerical examples, many from the Financial Mathematics literature, that show the capabilities of the method under very different situations.
