Another human analogy could be: you take a photo from every art show and museum, and use those for reference as you paint.
My understanding of neural networks is that there are no remnants of the original inside it. The training data is used to back propagate a bunch of weights.
Your brain works like those neural network neurons; they learn when to fire, but they don’t know the intricate detail like a photo. Hence why many claim eyewitness testimony is bogus.
Can you prove that? I can prove the opposite.
