Machine Learns Games

    Yes, you should. The computer deducted how to play the game on its on. Chess computers like IBM's Deep Blue are programmed how to play chess and beat opponents before playing, and here, the computer doesn't even know how to play; it learns by picking up the sequence of events (the human players say "rock, paper, scissors, who wins or lose") and then forms the ability to play.

    Doesn't this seem like A.I.? Rather freaky, to tell you the truth.

    It recognised 3 actions, and deduced that it had to pick one of the 3 at random
    No. It deduced that rock beats scissors and scissors beats paper and paper beats rock. It learned how to determine who won. This has nothing to do with the machine learning strategy.

  3. Strategy to RPS by Neo-Rio-101 · · Score: 3, Interesting

    This is nothing special. I remember my elementary school's Apple ][GS learning how to play 5-in-a-row or noughts and crosse
    s from this program called "AI".

    There IS a winning strategy to rock paper scissors, but it only works when you have a round of games (say best of 3, or best of 5)

    Initially, the first game is completely random, but reserachers found that if you chose the play that your opponent chose in the round before, you stand a 70% chance of winning the next round.

    It has something to do with how the human brain works.

    It's also something the Japanese taught me cause they play this game so much!

    I'm not really sure how "Learning 'rock, scissor, human'" became tantamount to "machines can spontaneously flow with free will and kill us all?"

    It's just a statement about AI, that's why it's insightful - lots of AI systems have historically learned the wrong thing, though we thought they had got it right. Like the neural net designed to distinguish between camouflaged tanks among trees, and tank-free forests. It seemed to work, until it was in field tests - turns out the pictures w/ tanks were all taken on cloudy days (or maybe all taken on sunny days) - the system had figured out how to tell if it was sunny or not.
