Beat Asteroids Game Using a Neural Network - JavaScript Tutorial

[@MtFordStudios]

Hi guys, thanks for watching. If you have any specific questions for me about the content, please ask them over at my channel kzbin.info as I don't actively monitor this one. Thanks!

[@PixelZYX]

THIS IS EXACTLY WHAT I NEEDED IVE BEEN SEARCHING FOR SOMETHING LIKR THIS FOR AGES THANK YOU SO MUCH

[@3stepsahead704]

I think watching Standords' Machine Learning course + this tutorial should be standar AI training for any developer. Thank you very much c:

[@brandonmartin1218]

You sir are a real GEM

[@crimsonzodiac908]

Really loving these tutorials

[@herbertk9266]

Thks nice tutorial, i have checked your channel it has alot of cool staff and i have subscribed

[@thomasbagge9585]

Thank you, this was very helpful!

Hi, Why you are putting the rotating algorithm and rules of playing and neural network together, if you are putting the rules of playing then there is no need for neural network. And I don't see the benefit for AI here in this example

[@anythingpeteives]

Yeah, just watched this and I thought the same thing. Couldn't see anything a neural network could do here that a simple bit of logic programming wouldn't have done.

@@anythingpeteives Hi, I see what you are saying, yes of course you could hard code the vector that points from the ship to the asteroid, turn the ship to that angle and fire and you will hit it every time. I think this is more about going through the process of developing a NN. If you think the inputs are position of ship, position of asteroid, angle of ship, angle to asteroid. During training the network feeds through all that data and compare the NN output to the desired angle, by feeding back multiple times and adjusting weights you get weights that make the output very similar to the desired for any given input. In the actual game using predict the same inputs go into the feedforward (the network knows nothing about what any of those numbers are) the output with the preset weights makes the judgement on the left or right turn. So what is going in is an array of data and the network makes a decision to turn left or right based on the output. Of course in this simple type of games you don't need a network but it does nicely show the principles in my opinion :-)

Thank u for this awesome video

Excellent tutorial 20/05/2020

Why not use genetic agorithm to train the model?

[@Stillbornzzz]

You could also do `Matrix.map(hidden, sigmoid) ` to not create a function each time you feed forward.

[@farenhite4329]

Aren’t GAs slower compared to reinforcement?

[@SunWKim]

No priority to preservation of the ship? I didn't see it turning around to defend itself from imminent collision. The Asteroids game does allow thrust. And in the arcade version, you have shooting UFOs that'd certainly kill the ship staying in a stationary position.

[@drtt1gg3r1]

He stated pretty clearly in the beginning several times that the neural network is only going to be coded for turning left and right.. He's leaving it up to the audience to take it to the next level.

[@mindaugasmaslauskas1213]

I've no idead what's going on.

[@peterfarrell66]

He’s going to all this work to train the ship to point at the nearest asteroid. I was hoping he’d use a genetic algorithm to train the net to play but apparently that was too complicated? It’s a good example of back propagation though.

Which is better to learn Python or JavaScript please tell , 👍If JavaScript Comment if Python And please do it fast I'm waiting

[@vatsaakhil]

Like everything else, it depends on which field you actually want to work in

[@sajateacher]

Both

[@hamrogarage4658]

Learn Both For front end use Javascript For backend use python and it can also be used in AI sector so Just learn both

[@noctavel]

why to use two different languages, if javascript can be used both back-end and front-end and have the same capabilities (maybe more ?) and performance as python?

[@DavidZMediaisAwesome]

@@noctavel i wouldn’t say it has the same capabilities as python, only because python is actually used for data science stuff more and therefore has more work put into libraries in that field. However, i totally agree that javascript should be used for both frontend and backend stuff.
