Python Pong AI Tutorial - Using NEAT

[@yubinxie4475]

Although I must agree the topic discussed here is not beginner friendly, the way you explained a lot of the details and even went back one point to reiterate what you wrote for the train ai script was extremely well done. Thank you for the tutorial!

[@krit6847]

Im addicted to your tutorials, keep it up Tim!

[@kamakura9722]

[@Djellowman]

To those implementing this: you will need the x and y velocity of the ball too if you use a ball speedup-mechanic (like i do) where the ball moves faster than the paddles. then it's not enough to simply keep the paddle y the same as the ball y, you need the velocity so it can predict where the ball will go.

[@Djellowman]

Coming back to this, it turns out genetic algorithms get stuck in a local minimum, with absolutely no way to get out of it. This minimum means that the model only learns to keep the paddle at the same height as the ball... So it's seemingly impossible to train a competent AI for Pong using a genetic algorithm if the above strategy stops working once the ball speeds up. Perhaps reinforcement learning would work, but i don't see how that would get out of the same local minimum.

[@Seedx]

@@Djellowmanweird, genetic algorithms are supposed to avoid local minimums. Is the speciation implemented correctly?

[@Apify]

Happy to support Tim's videos - keep up the great work! :)

[@astrovation3281]

Thank you so much! I've never done anything with AI before, so even if this is hard for me it'll probably be very educational.

[@jamieharper5665]

Amazing video thank you! Had an issue with the data printing but then realised I was just being impatient and needed to wait lol. I can't tell you how useful this was as an introduction to neural networks for me 😁

[@fhtagn20]

Your tutorials have really helped me improve my programming skills Tim in a way I can't put in words. Thank you so much!

Bro I was looking some tutorial to make a pong ai using python at 2 days later ur video is here love it and don't know how you know what the views want thnx alot

[@TomDoesTech]

This is so cool! Awesome tutorial

[@kiat4797]

love ur videos tim . i have been Following u for a long time ( probably 3 years ). i love how u're explaining various concepts clearly and smoothly and i would love to see u creating a ray casting engine or ray tracing engine in pygame . a lot of fun math ( linear algebra , geometry ... ) and some cool physics concepts to discover while coding it

[@Nimnimpac]

If I am correct in around 49:50 you lower later genomes fitness. Lets say we have 3 genomes. We set genome1 fitness to 0 in first for loop then in second for loop test it against genome2 and genome3. After this genome1 has fitness 10, genome2 fitness 4 and genome3 fitness 6. The we go to genome2 and set it fitness to 0 but due to second for loop " in genomes[i+1:]" genome2 wont play against genome1 now only against genome3 so it will have lower fitness.

[@HcmfWice]

Yeah, I’ve noticed this as well. Also, genome1 only plays on the left side (and the last genome only plays on the right), while all the other genomes play on both side. A simple fix would be to iterate over the whole range in both the outer and inner loop, and in the inner loop make sure that the two IDs are different (if you don’t want the genomes to play against themselves). It really says something about the robustness of evolutionary genetic algorythms that it still produced a genome that plays well.

Hey Tim, thanks for the great video. Would love to see more cool things with AI and NEAT

[@lorenzofiore7438]

Just finished the video. I can't wait to actually start writing some code. Firstly on pong and next on some random game i'll find. The cool part about neural networks is that they do all of the hard work for you by optimizing the output without knowing what it is going to be used for. They just adjust weights and biases waiting for a treat 😂. Unfortunally for genetic algorithms they are going to die without being rewarded 😢😂. Thank you for the video.

[@goranjosic]

I'm working on my first NEAT AI project, and this tutorial is very helpful because the documentation is quite scarce. Before this video, I watched a NEAT AI video by sentdex channel, and it's quite bad compared to this one - his video is literally a copied example from the documentation, without any new explanations - it's just not worth watching, it's better to read the documentation, than to watch his video - my experience. Overall, good tutorial!

[@xGino_n]

@@heelercs don't know man, but this technology is kinda cool and futuristic. If we could master it and combine with the 3D modelling and printing to create human looking AI robots, then the world could turn into a Terminator

[@heelercs]

@@namashaggarwal7430 Agreed, it is really cool technology. Unfortunately it's almost always seen as a harmful technology (for now). I doubt Tech With Tim would want to publicly associate with something that's almost always associated with pornography.

[@namashaggarwal7430]

@@heelercs every technology in the world has 2 sides , one is positive and second is negative. To exemplify, nuclear technology can be used for destruction of a nation using nuclear bomb but on the other side, the same thing can be used as an excellent carbonless energy source for the construction of the humankind. We must need to make certain rules and protocols for each and everything to keep a positive balance. It all depends on us, how we make use of it.

[@heelercs]

@@namashaggarwal7430 I never disagreed with that. However, just because two sides exist doesn't mean they hold equal weight. To use your own example, surely you don't think that the positives and negatives of nuclear bomb technology is equal? There's definitely much more potential negative harm than positive harm. Since we're going to extremes, gas chambers are another example. Surely you don't think the positive and negative are equivalent, right? So my point still stands.

[@jantonisito]

Maybe you could do part to and analyze how those NNs evolve. The key point for me was that some randomly generated set of connections will produce some output (three numbers) . We CHOOSE to interpret these numbers as movement of the paddles - order of stay/up/down is arbitrary. Once we chose some interpretation we apply it to paddle movements and we asses if given NN (given genome) actually makes good decisions (is more fit). What is completely elusive for me is how they make a decision to merge network topologies - without some actual analysis what changes in structure could be responsible for performance improvement - how do you pick up what to merge? Either way very good tutorial - thanks! PS. If your generation runs slow definitely turn of screen rendition during training - program runs ~30 times faster. Also I found out that limiting exchanges (hits) to less than a suggested 100 speeds up hitting the target fitness. With 70 limit I hit 430 fitness in 18 generations.

[@drydenstewartenterprises]

Hey Tim, Thanks for the video! I was wondering though, because you used NEAT with flappy bird, and now with pong, is neat used just for games? I've been learning Python through you and Sentex and neuralnines videos for the past 2 years and I have learned a lot but I still have a long way to go, I am interested in building some of my own small robots and I am wondering if you would ever work on a series about incorporating computer vision with a voice assistant and some form of AI (maybe neat?) so my little robots can recognize objects and people, and tell you that it has recognized those objects or people?

[@ravenblackspike]

NEAT would probably not be useful in that particular use case. You would be better served by a couple of discrete models with code that passes your inputs to the models. Something like the below. 1) Computer Vision model for object recognition. 2) Speach recognition model, TTS model for the voice commands and output. 3) Whatever code you would need to handle moving the robot/passing inputs to your models.

[@ethitlan]

Hey Tim, I have a question. Does the frame rate you train it with affect its performance? I've been training it with no frame rate cap for a long a time until I played against it and it wasn't as good as I hoped. So then I changed the frame rate and (although it was humanly impossible for me to play the game) the AI did MUCH better at receiving the ball. What do you think?

[@Djellowman]

good question. yes it does affect the performance, as it gets more input and actions per second if you have a higher tickrate. But i'm surprised to hear it's a big difference.

[@Djellowman]

actually, if your tickrate is tied to the framerate, it shouldn't matter. It means the game speeds up as your tickrate increases. So actually, no it should be identical during training and playing against you.

[@ethitlan]

@@Djellowman oooh then perhaps my tickrate was different. Thanks for answering Tim!

[@ChrisJames-tf8yw]

Awesome video. Now can the AI be created that moves the ball x,y position. The future should be code-less apps. I want to try make a Python training that would make the AI generate the ball x,y coordinates for the game. But could this be done without coding as well? Could an AI be trained to watch a pong game and then be used to train the AI to control the ball x,y?

[@Gunsi-kb2xq]

for me it creates only 1 ID per generation... is this OK? Tried your code as well but aways only 1 ID after every generation...

[@danilotrix]

This was amazing. Thanks so much. 1 question. What about rewards? You didn’t mention it or I missed it. How do they learn the right movement to do? Thanks

[@NinjaTxGaming]

Reward is the fitness variable. Tim set the reward to the number of balls hit in total throughout all the games.

[@ninek1902]

Hey Tim, I have a question about the oscilating best fitnesses... How is it possible for best fitness to drop in comparison to last generation if there is elitism involved? In your config the elitism parameter is set to 2, which means 2 of the most fit individuals from each species will get pasted in the next generation (according to neat-python docs), thus the algorithm is not supposed to score lower than their previous score...

[@mmdrlolfr2612]

I think it's because if the first genome gets a mutation, his fitness can decrease and if nobody has exceeded the previous best fitness, the global fitness will just decrease. Or maybe it's because the first direction of the ball in pong in random and maybe the first genome got an extremely good luck and that didn't happen later.
