METHOD.
1. Work out what each part of the network computes from the weights: which layers, units or directions matter, and how they fit together.
2. Do not settle for trivial statistics: norms, ranks and spectra show where things differ, not what they do. Base your answer on what the network computes, and do not stop at the first plausible signal.
3. Print compact summaries, never whole arrays; output is shown in ASCII.
