There are essentially two main options to remedy this: 1. Find ways to perform active inference, so that the model adapts its learned program in contact with a new data distribution at test time. Would likely lead to some meaningful progress, but it isn't the ultimate solution, more of an incremental improvement. 2. Change the training mechanism to something more robust than SGD, such as the MDL principle. This would pretty much require moving away from deep learning (curve fitting) altogether and embracing discrete program search instead (which I have advocated for many years as a way to tackle reasoning problems...)
