  • I trained an AI in Trackmania with reinforcement learning, until I couldn't beat it.
    I just opened a Patreon page, where you can support this CZcams channel with a donation (link below). Between research, programming and editing, these videos take a long time to produce. Any support will help me to spend more time on that in the future ! This one in particular took up most of my time over the last six months. I hope you like the result, and I'm open to any feedback to improve the quality of these videos :) I'll post more details on the Patreon page to explain what I plan to do next.

    The main problem with the final test is that this part of the map was still contained in the training data, and for that it means it likely doesn't generalize and instead was over fit at least slightly

    • @jolemackerel
      @jolemackerel Před 5 měsíci +86

      It doesn't seem like a problem, just a known constraint on this solution.
      Technically speaking: say the AI trains thousands of times on each track in existence. It has the capacity to store track-specific data and total, general experience training data. Would it be over fit or appropriately generalized for its purpose?
      Philosophically, is it that much different than a human player with "favorite" tracks, ones that gave the brain the best feelings to repeat and learn?

    • @jsanchez23
      @jsanchez23 Před 4 měsíci +40

      Pretty sure that wasn't the point of the final test, as proving generalized success was already determined to be a much harder task. The final test appears solely to prove if the ai truly was driving/performing faster than him or if it was just its consistency giving it an edge due to all the human errors and mistakes a person would make in such a long track.
      So the final test was realistically just meant to be the exact same test as the full map, but with the potential variable being changed being himself as the player. As it seemed more likely a scenario to further "perfect" or at least minimize as many mistakes from their own times on a smaller snippet of map..
      Which wasn't exactly a viable option to avoid so many mistakes on such a long track, with many opportunities for mistakes. Which is also likely why he mentioned that there are surely far better players that could beat the ai on the final smaller track snippet, but he had doubts they could beat the ai on the full size track. As on a track that long any human is bound to slip up and make mistakes with that longer frame to go so far without any mistakes, giving the ai a chance to catch up.
      While still possible, it would take a lot more practice and luck.
      So the task of further generalizing and making the ai successful on any track, is a task and test he hasn't actually truly delved into and realized was fully beyond the scope of this video and will likely be tackled in the future.
      So the final test really did just serve to further demonstrate the ais biggest advantage was consistency and before training it to drift, it wasn't actually driving faster or "better" at all, it just wasn't making the countless human error based mistakes that a player would. Since once transferring to the snippet map and practicing out as many mistakes as he could, it began to close the gap and was being outpaced/raced by him.
      Then the drift training proved to again close the gap towards actually driving more effectively, but still appears could be outpaced if a player was able to pull off their best version of a perfect or no mistake run.
      Since like in speedrunning, its easy to have an incredibly skilled player that is well practiced and capable of playing the game quite well, but runners will often have countless attempts, given the numerous frame perfect or otherwise precise moves needed and they have to make all of these numerous separate and precise moves all in the same run. So if you have an ai that can flawlessly and consistently pull of those specific frame perfect moves every time, you could say the ai is faster, but the speedrunner is still likely playing the game as a whole better and the gameplay between those moves is likely faster and better performed, but its easier to make those individual move based mistakes and if they were removed from the equation, the player would likely be faster than the ai with their overall gameplay.
      So the final test was just trying to remove that same mistake based advantage to the best of their ability, in hopes of improving overall fitness/skill over mere consistency.

    For the AI to be able to reintroduce its new isolated drift skill to its arsenal after the reward was removed is so cool to me. I feel like that is such a massive way to teach AI new skills.

    Really interesting approach to have the AI train with a "wrong" reward for a while to overcome a local maxima hard to find ways out of otherwise. That feels like it has some really good parallels to human learning, where a good teacher can help you immensely in how quick you learn something new. Or how athletes sometimes train using special limitations or disadvantages to improve their ability in specific cases in their sport - all to be better when they go into a normal competition.

      There are many cool approaches to fix local maxima problems, usually inspired by real life processes.

    To make it more robust, it could be interesting to add a variety of extra conditions:
    - you are already spawning in random spots but you can also spawn in random states, i.e. in different orientations and speeds, possibly including upside down so it has to learn to turtle and recover (where that is possible)
    - in addition to the lateral motion reward, you can try somewhat randomized state rewards (reach weird parts of the state space)
    - or even exploration rewards (you can basically do a coarse histogram of all possible internal states and then reward it for even coverage of that histogram. Rather than as fast as possible, it should be driving in a way that finds as many states as possible while still finishing the map.)
    - or action constraints (disable breaking from time to time. Disable *forward* from time to time so it has to learn to deal with backward driving. Maybe occasionally even disable left or right. It's also possible to do "sticky actions" where you just randomly make it commit to an action for a few frames rather than being able to change the action every frame)
    - or senses (disable some of its inputs either by zeroing them out or by sending random noise through them)
    - or road conditions (you already mentioned those so I'm guessing your next video is gonna tackle that)
    - or physics (you also mentioned this as well)
    People have also experimented with a very weird robustness strategy where you basically add spurious inputs (they just get noise as input) but then *shuffle around which input corresponds to which value* so the AI has to learn to spot patterns in the inputs to figure out what those inputs likely mean before actually acting upon them.
    All of these together, or even just a solid subset, should make for a really robust and multitalented AI that can theoretically achieve just about anything that can be achieved in the game. Like, in terms of finding the state. Not necessarily yet in terms of beating world records. And then, once you have that, you just finetune that basic broadly capable AI without any of these constraints on any map you like. It'd basically be what you did with the drifting here but training it towards much broader capabilities as a starting point.

      Can you explain the spurious inputs strategy further please?

    • @Kram1032
      @Kram1032 Před 7 měsíci +17

      ​@@owendeheer5893 So I don't remember what particular network style they chose for this. I think it was a recurrent neural network? But anyways, the basic idea is pretty simple:
      In addition to all the inputs that already are there, you add a bunch more. (Say, three more neurons or whatever)
      Those extra inputs simply get fed random noise, so they aren't going to be meaningful to the training what so ever.
      But the twist is, that you then ever so often (after, say, a second) *randomly swap the order* of those inputs so the layer after doesn't know for sure which input is which. It has to figure that out based on the received signals.
      That way it learns not only to relate input patterns to output actions, but necessarily also what typical input patterns look like. It has to work way harder and "pay way more attention" if you will, to still get a meaningful result.
      IIRC the idea was, that you can use this to make it possible to extend the network after training. Like, instead of noisy inputs, you can then add additional actually meaningful ones, and there is a chance the network manages to generalize over those additional inputs.
      To be clear, I don't actually think that particular augmentation would be useful here. Most likely, it *could* be, but it would require a larger network just to allow for the overhead of internally swapping around the data to be routed correctly. IMO the most powerful ones I mentioned are likely to be the road conditions and physics tweaks alongside the histogram over state space (that's somewhat related to Map Elites, although that's an evolutionary algorithm so not quite the same. I think there is a variation of that which is meant to work in this setting though. Differential Map Elites or something?)
      Simply increasing diversity (i.e. training over multiple maps at the same time) is also likely to give rise to gains, especially paired with a curriculum so easier maps are experienced earlier and more challenging ones later. (Very challenging maps initially will only cause a lot of noise slowing progress even on easier maps, until the AI acquires some basic skills. Definitely don't train it on Kacky maps right away lol)

Which seems only usefull in cases where you want the network to learn statistical things, or you want to force the network to encode information in certain "interesting" ways.

      I don't know how well this approach works in terms of generalization. I have serious doubts on it working on any maps that are designed different from the twisty horizontal characteristics of his current test maps. And if he manages to get them working on different maps it will become much slower on the current ones.

    • @BigDBrian
      @BigDBrian Před 7 měsíci +13

      @@timbraska6750 I think for the AI to drive well on a variety of maps there needs to be some solid foundation to start off with, then some training on individual maps. This is also fair to human play since we play maps over and over to learn them specifically, while having a lot of experience in general to back that up.
