One of the paclets required for running this project is not included in the current version of Mathematica therefore if you want to try this project yourself, you can wait for the release of the next version. 11.3 or 12? Not quite sure when they gonna release this patch. Since the current version of neural network function does not support features such as train two networks at the same time or custom loss function combining multiple inputs. But feel free to ask me any question about this project
