    Code Bullet really is the best inspiration. He doesn't hide or gloss over his mistakes and in so doing shows that coding really is a perpetual state of learning through trial and error.

    Neat detail I noticed that wasn't brought up. At 2:46 you can see the player square falls all the platform a bit early, when it's only halfway off, which causes it to clip into the floor a bit. This is because the "laser" vector that detects if the floor is there is positioned in the middle of the square, and therefore doesn't detect the ground when the square is only halfway off.
    This is silently fixed at 2:58, where the square now only falls when it's fully off the platform. As you can see, the lasers are on either side of the square, making sure both have to be off the platform before it falls.

      There's test-driven development, where you write a test for everything that should and should not happen, e.g. jumpman jumps at least once per game, and over time more tests pass. It's a lot of work, but the benefit is it will catch regressions; as we see here when Jumpman sometimes flies into the air after Code Bullet thought he'd fixed gravity issues.

    PPO is basically strapping the AI to an N-dimensional sled and punting it down the N-dimensional hill. You need to choose how big a sled to use, how much momentum to conserve, and even how the hill looks like. And in the end when you think you reached the bottom and looking for an N-dimensional cable car to take you up for more you find out that you are in a shallow N-dimensional depression somewhere half way down the N dimensional hill. Where N is the amount of weights you are using.

    I'm quite impressed with the second algorithm (NEAT). That algo figured out to ignore a couple of the inputs, generated a tiny net with only 3 nodes across two hidden layers, and was beating the level without hitting the jump button. Say what you will but I'm more impressed with that than the last algorithm.
    Awesome video!

    • @LutzHerting
      @LutzHerting Год назад +28

      Yeah, NEAT is pretty neat... (*groan*) One problem with it is that it often throws away good solutions because the mutation can often be quite aggressive and throw out long-term positive traits for short-term gains. That said: This is literally how real-world genetic evolution works too. So for this algorithm, it pays #1 to have bigger population sizes, #2 to be careful about your mutation rate, and #3 to give it enough time to run. In all experiments I did with it, it often reaches a plateau where not much happens for many generations, but after a long time, it suddenly starts improving again. I'm pretty sure it has to do with the "species" system it uses: Often, one species is so good at what it does, that even "geniuses" in other species don't have enough impact to lift their otherwise mediocre species above the king of the hill species. This can lead to situations, where species with the potential to become the new best species die out before ever getting the chance to reach their full potential. So, like I said: It works just like natural genetic evolution... A species doesn't automatically survive just because it is fitter. There also have to be the right set of random circumstances to allow them to succeed.
      P.S.: One interesting experiment you can do with NEAT is to have to mutation rate ALSO me a trait that can be mutated. That leads to some low-mutation species that keep SLOWLY improving their positive traits and several high-mutation species that keep trying out random stuff. This stops a typical problem in machine learning: The algorithm settling in a "just-good-enough" plateau instead of keeping to improve in the hopes of finding an "even better" plateau further down the line.
