I think your questions all grew up in a world where the people operating the thing knew some rationalist who could think deductively about its operation. But neural networks... they're an exercise in empiricism. We only ever understood that it works, never why. It's sort of a miracle that it doesn't produce buggy output all the time. What do you tell people when they want to know why the miracles have stopped? Root c…
“We don’t understand why neural networks work” is a myth. It’s not a miracle, it’s just code, and you can step through it to debug it the same way you would any other program.
Sure, you can "step through" a neural network but all you'll ever see are arrays of meaningless floats moving around.
