That's not how neural network training works. It's not magic or guesswork; it's essentially glorified curve fitting (over a much more complicated space than the polynomials). It's also not random in any respect. The space of all neural networks plausibly generated from a training set is very, very small compared to the space of all networks of that size.

- Nevermark 10y agoThe initial conditions of neural networks are almost always chosen randomly or pseudo-randomly. Data sets are sometimes, although not always, presented with random sample order or selection. Either way, the randomness in initial conditions means the solution found is one of many different solutions that could have been found, and depending on the problem, different initial conditions can result in very different solutions even on the same data.
