Last year, Facebook open-sourced graph transformer networks (GTN), a framework for automatic differentiation with a weighted finite-state transducer graph (WFSTs). To put things in perspective, GTN is to WFSTs what PyTorch is for automatic differentiation with tensors. GTN can be used to train graph-based machine learning models effectively.
