AlphaGo's weakness was stated in the press conference inadvertently: it considers only the opponent moves in the future which it deems to be the most profitable for the opponent. This leaves it with glaring blind spots when it has not prepared for lines which are surprising to it. Lee Sedol has now learned to exploit this fact in a mere 4 games, whereas the NN requires millions of games to train on in order to alter its playing style. So Lee only needs to find surprising and strong moves (no small feat but also the strong suit of Lee's playing style generally).
- conceit 11y agoYou are saying, its weakness is making the mistake of not looking at all the profitable moves. The contra argument for the sake of the argument goes, he just was lucky to find a local maximum (?) outside of the search space (?) by chance, rather than learning in a few days the universal function (?) that the NN thinks solves go, or at least one fixed point (?) [i.e. the surprisingly wrong expectation].
