   Yes, there is hope for a high-level heuristic understanding. Here's my attempt to explain in more familiar terms. They train a new neural network from scratch for each problem. The network is trained only on the data about that problem

   I've also been surprised many times by issues in numerical libraries. In addition to matrices with simple entries, I've found plenty of bugs just testing small matrices, with dimensions in {0,1,2,3,4}. Many libraries/routines
