[@Kram1032]

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.

[@Amelia_Scp_and_Halo_fan]

good idea

[@owendeheer5893]

Can you explain the spurious inputs strategy further please?

[@Kram1032]

​@@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)

​@@Kram1032 "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.

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.

[@MrMeasaftw]

@@inthefade The true challenge would be the pathfinding. An untrained AI would take billions(if not many factors of 10 more than billions) of simulated years to figure out how to drive the map. So you would either have to start the ai with a reinforced path like Muddas run. Or have a godly pathfinding algorithm. Otherwise the AI would just start driving the wrong way.

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. Awesome video.

[@Kyrazlan]

Same principle in life. You can learn from mistakes and failures and take away positives from them. A full technique may not work but partial techniques can be applied in certain situations. It's the foundation of bruce lee's martial arts. Learn as much as you can, use what works best. There's not really any downsides on iteration.

[@xXErr4rXx]

There are many cool approaches to fix local maxima problems, usually inspired by real life processes. For example one method is inspired by how a heated metal cools down and the excitation of the particles, the algorithm has a large chance of picking a random option instead of trained one and that chance decreases logarithmically as time goes on, to not get stuck at first but expecting to settle as time goes on

[@kootenpv]

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

[@falinoluiz5962]

Slightly? Bro the whole thing is overfit lmao

[@jolemackerel]

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]

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.

I really find things like these impressive and very Interesting how ai works when learning😊

[@gamer__dud10]

❤❤😊❤😊😊🎉😊🎉🎉🎉🎉 ❤Truly truly i say to you all Jesus is the only one who can save you from eternal death. If you just put all your trust in Him, you will find eternal life. But, you may be ashamed by the World as He was. But don't worry, because the Kingdom of Heaven is at hand, and it's up to you to choose this world or That / Heaven or Hell. I say these things for it is written: "Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, *teaching them* to observe all that I have commanded you; and behold, I am with you always, even to the end of seasonal". Amen." -Jesus -Matthew 28:19-20

J'ai examen d'introduction à l'IA demain matin, je viens de te regarder expliquer toutes les étapes de reinforcement learning et les illustrer en faisant du TM, c'est parfait. Merci, je comprends et visualise beaucoup mieux cette technique d'apprentissage et ça permet de se rendre compte de la beauté de cette méthode

[@1by110]

hooked till the end. Amazing work explanation and visuals man

[@pr0hobo]

I cant wait to see generalization. I hope we can see a full ai playthrough of tmnf at some point if this keeps going.

[@Pandize]

Yes. Beyond million view title.

[@whirled_peas]

Just hope it doesn’t generalise too much or it will push us humans off the planet

[@kazuala]

There's a streamer on twitch that already does this with the Name: PedroAITM

[@timbraska6750]

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]

@@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.

[@nonso8647]

I loved everything about this. The story telling, the pace, the visualization, the editing, AI. Absolutely brilliant video. Keep up the good work

[@archangel1730]

Excellente vidéo ! Ça fait plaisir de voir quelqu'un de passionné qui fait en plus un gros effort sur la forme ❤

[@shashwatpranav2313]

That's why I like KZbin, this video was just amazing, and Kudos to you for putting such an effort

[@chaseconnor1959]

One of the best KZbin videos I’ve ever watched. The time and effort this took is commendable to say the least

[@blackhole927]

As a non-trackmania player who’s been keeping an eye on this series over the past few years, it’s amazing to see the AI drive so well! Amazing work!

[@lululumacat]

same yeah trackmania seems cool but I've never played it much. I was super happy to see the ai was able to beat them after all these years tho!

[@Known_as_The_Ghost]

9:44 This editing was sick. 10/10

[@Rxspcttt]

this is probably top 5 videos ive ever seen. ive never been so interested in something while watching. gg's dude

[@jcorey333]

I like the color coding! Also, I think your idea to give it a specific reward for a certain skill, then taking that away once it mastered the skill, is really genius! Did you get that from a paper? It definitely belongs in one. Kudos to you!

[@MorzakEV]

Yeah, I guess that’s like when humans break learning down in to specific skills for a period of time before putting it all together again later.

[@TheShazMC22]

It’s like positive reinforcement when teaching children or a dog. You reward it for doing the right thing until it does it naturally. Pretty cool

[@SimoneBigozzi1998]

I have been waiting 3 years for your update on jumps and generalized maps, I will be there in another 5 years. Congratulations on your great work, this is something I also tried to do in 2017, without any prior ML knowledge. I failed and abandoned the project, it's very hard to accept failures like you did in these 3 years, but the rewards are awesome!

[@dr.skillz77mgpl92]

Very good video quality, very well explained, calm voice, insane skill, legendary editing, and high intelligence from this channel. One of the most qualitative videos on KZbin, it really feels like you put A LOT of effort into this

[@MarisaLindsay]

THX FOR ALL THE DETERMINATION OVER 3.. WHOLE.. YEARS to make this video

[@patriceducharme1144]

Bravo pour ta détermination ! Quelle aventure. La narration et le montage sont dignes des plus grands. Encore une fois bravo pour ta persévérance. Ne lâche rien et les résultats viendront d'eux même !

[@rafaelzhou4749]

D’accord!

[@ninjanolan6328]

Ouais!

[@metropolis10]

What an amazing effort, I was most blown away by the presentation and editing! Well done.

[@younglife88]

i don't know how I ran into this, but amazing way to showcase AI, how it works and a very passionate player going the 'extra-mile' to make things they love, even better. true mastery of a subject. well done!

[@abdullahalam2088]

Very very well done video, thoroughly enjoyed it. Excellent content, excellent structuring of the video itself. Loved it.

[@MrRubikraft]

Chouette projet, bravo !

[@tyrereviews]

This is one of the best videos I've ever seen. Amazing work ❤️

[@petertorok7341]

I am studying in the fields of deep learning, neural networks and this was one of the most well put together and well explained video I have ever seen. Incredible graphs, and explanation. Thank you

[@manuell3505]

How is this not just trying all options with mass computation? I don't think there's anything that can be considered AI.

[@yaroslavl6336]

This is sick! You’re the sick! I mean dude you’re really should to apply with this to various ai teams! You’ve done such a science here!

[@bredgefox1599]

Félicitations pour tout ce travail accompli. Je suis persuadé que si tu continue en cette voie tu finira par obtenir une IA performante sur n’importe quel type de map. Qui peut-être même que ça finirais par attirer l’attention de Nadeo ;)

[@Ciboullete]

Un Français sur une vidéos américaine ? Étonnant !

[@Ciboullete]

Qui est Nadeo ?

c'est parce que yosh est français

Dude! I'm so happy to see You back! I love your content and i can't wait to see AI trying campaign maps haha

[@RickVegasGames]

That’s incredible, it’s like watching your student grow and it’s at the point where it finally surpassed you.

[@deanvangreunen6457]

Amazing dude, much respect, well done bro

[@MalrusOSC]

These are the ultimate KZbin videos. Secretly educating you in some way disguised under a very entertaining video.

[@sandeepnautiyal3070]

This is rather beautiful than being scary and gives a sense of wholesomeness. It's like you being really the greatest in something like chess, football, boxing and then you start to teach your kid and see them in a few decades be even better than you.

[@faltice1314]

Je ne joue pas à Trackmania, mais le travail que tu as présenté est monstrueux. Félicitations
