NES AI Learnfun & Playfun, ep. 2: Zelda, Punch-Out, stocks, etc. 

Isn't weird how you put a personality to the AI inadvertently

Seriously cool program but it's kinda disturbing watching it get the code version of an endorphin rush every time it stabs a human

"Doesn't care much about bytes going down, only about bytes going up.." PlayFun is an inspiration to us ALL!!! This is how we should live.

well, you know how to end videos, that is a fact

This mini series is the most interesting stuff ive seen in a long while!

Your commentary is what makes this. Brilliant and hilarious at the same time.

Learnfun vs TwitchPlays

I find it rather cute that youve called it a "he" several times and its main goal is to get bytes to go up and it can do this by just wiggling a cursor and its happy

The computer program is a genius at times, it learns so well! And your commentary and little inserts of funny skits is amazing! I laughed pretty hard XD Thank VSauce for showing me your videos!

7:17 Earning a star gives you an additional 100 points, so that's why it was so intent on getting stars.

Well that's rude.... I happen to like your explanations along with the gameplay. Don't take what the youtube comments say to heart, the internet is full of douchebags. This is one of the coolest things I've ever seen.

"should I read the paper? Should I touch the computer?"

I think it would be interesting to add a praise button of sorts where you can tell it if it's succeeding or not and see how it affects it

Dude this is great stuff, I laughed, I cried, etc. And most of all, I'm disappointed that people turned you off of talking about the CS and the math! that's the most interesting part to me.

that 'but he didn't say I couldn't do drugs' line took me so off guard haven't laughed like that for a while

20:29 "And Playfun get's stabbier and stabbier as time goes on" I couldn't stop laughing at how much it was just stabbing away xD

Mark my word, this is the next evolution in lets plays, "Let AI Play"

i almost die at the end, jajaja greeting from Chile, great videos

There is something so adorable about this

This is the most interesting and entertaining thing I've found on youtube in a while. Great job, you created AI and accidentally gave it a hilarious personality lol

"Maybe he is waiting there to the cold war to end" I'm fucking dying xD

how satisfying it is when something you code that works even partially

It's funny how most humans have curiosity to go into the first Zelda cave before walking away, yet the computer doesn't care or know what that is.

Dude, this is amazing. Actually letting a machine learn how to optimize objectives by "learning" (genetic algorithms, machine learning, neural networks) is a very popular thing, but the fact that really amazed me is how your algorithm is incredibly good at finding bugs and glitches in its favor. The fundamental idea of science is the discovery of stuff in nature that doesn't make sense and the need for humans to understand it. Your algorithm lets the computer do the job of finding this stuff. As a fellow computer scientist and being as stoned as I am now enjoying your video, congratulations and keep it up!

Extremely enjoyed this episode, cryed laghing watching this episode.

I haven't had tears of laughter in years, but this did it

i love your commentary, its good for chuckles that don't make me miss information and have to rewind, also, it never feels like you're forcing the humor of the situation. Please keep these up!

I just love how the AI doesn't care about dying until his last life.

Anyone else notice the cheat Playfun does in Punch-Out! at about 8:00? He does 2 super uppercuts and only loses 1 star.

I'm sorry that I'm 9 years late, this is quality content!

"It drowns it's sorrows in dog shopping." XD I can't... I can't even...

I love the image of a daft punk style robot sitting in a wall street office, doing nothing for a few days, suddenly getting up from the desk one day to buy a dog, coming back, buying some stock, and then sitting idly for another 10 days while it continues to lose money

i love how the AI becomes really "sad" whenever he wins in punch out

I initially watched this to get a grasp on the whole 'only winning move is not to play' thing - after / during a conversation i had with a friend about whether or not war is a viable response to things like 'terrorism' .... (war...thermonuclear war.... etc) ... and now I am hooked on how this AI learns and plays stuff!

That ending was great. lmao

I loved the live action parts of this video. Really great.

This is my favorite thing ever

I'm not going to lie, I did get a few good laughs out of your commentary, and even live acting, but I honestly think I appreciate the more serious approach like in the previous vid more. Don't be afraid to nerd out and get down to the true value of this technology. I feel like the comedic approach, although entertaining, undermines the value of what you've made here, and turns it into a joke. As you've said, this is not an April Fools joke. It's real work, with a real purpose.

This video is funny because of the way that the computer tries to work out things, especially with the stabing that it does in the game at the end. Just decided to cling onto the ladder, move up and down a little bit and then proceed to flying crouch stabs to the enemy LOL

Finally, the difficult but necessary work of playing Nintendo can be carried out on our behalf.

Computers playing video games are so cute for some odd reason xD

Dude....this is EXTREMELY interesting as well as hilarious. Bravo.

18:19 "Russians, they were like - all bad." And so the pendulum swings...

the last final seconds are amazing

So it learns from it's own mistakes and improves? So, given enough time, he could beat any one game flawlessly?

Lol Tom you are such a good game commentator this was both hilarious and fascinating at the same time

Your programs are amazing and you are completely hilarious! I could not stop laughing. I would love to see many more of these!

As an undergraduate CS student who studies functional languages, I really appreciate what you're doing here.

The graph shows a lot of bytes increasing when he's on the ladder (such as at 19:35). Does that mean that the program believes it's getting points on that ladder?

Oh man, 16:22 and 22:10 I lost it. The little skits are hilarious. Fantastic work, dude.

This is great! Love those parts where you acted it out, haha. Vsauce brought me here.

Your humor and sarcasm are admirable, the playfun imitations are really great.

Those stabbing skills are amazing though xD

"You don't need to worry about this thing taking over" oh Tom, if only you knew

This is amazing, can't wait for the rest. The commentary is very funny, good on you.

Oh my god this has to be one of the most hilarious things I've seen this year and I don't know why.

I'm sure that other people have asked the same question, but what would happen if you programmed the AI to care about points going down as well as going up? Would that make the AI more careful in games? Or would it be too careful and just avoid everything?

I lost it at the wall street game... amazing.

42GB OF RAM BEING USED‽ WHAT ARE YOU‽

Can I ask a few questions?? 1.can it self learn from its mistakes? 2.is it easy to set up the program or can you make a video about it

Your voice is so relaxing.

I love the humor so much!!! Please keep up the amazing work! this is not only very interesting but very entertaining and funny

Im 7 years late to this but its an incredible thing Im wondering if there is a way for playfun to pickup where it left off after being run after closing the program so you dont have to restart from frame 1 again

I actually got how it works! Learnfun watches you play the game, and it keeps track of the techniques you use, and uses those technique to his advantage.

"Watch this advance stabbing technique" made me laugh really badly you are awesome

Dude.. you don't get enough credit for what you've done. Your views should be in the hundred millions, this is really really cool watching an AI play games is very interesting and trying to see how it solves it. Lookin forward to new videos about it :)

Burst out laughing at 3:45

How do you set the coefficient of the proportion between objective function (game score) and the pixel change rate (or happy, sad score). Is that part of the optimization ?

best end ever ^^ man 2 videos and i had to subscribe. your doing a great job

Watching your hand twitch slowly over the keyboard was the funniest thing!

This is better than TASbot! I don't think I've laughed that hard in a long time. "Well maybe. I feel. STABBY." -PlayFun 2013

I like how learnfun found a game in starting the game.

Very interesting, and really pretty funny - your re-enactments are appropriately awkward and spot-on! I think my fav part has to be at 20:45 - that crazy stabbing spree had me waking up my S/O with hysterical giggling. Do you have any plans to extend the software in any way, make it capable of understanding more concepts, planning further ahead, and so on? Or perhaps being able to figure out how to play on its own, without the need necessarily for you to demonstrate it beforehand? I realize it'd be a lot slower that way, since it would have to more or less randomly discover favorable moves and techniques to a larger degree than it currently does. At least that's my understanding, that right now, it puzzles together small sections of moves that you've done? I did just watch part 1 beforehand so you'd think I would know the answer to that...! Either way - I'm not a computer scientist or into AI so it goes slightly over my head, but it's fantastically interesting anyway!

22:00 LOL, the satisfaction meter follows the music!

It's sooo happy when it's playing Dr Mario badly!

That "douchetrader.exe" footage forced me to hold my breath because i'm supposed to be doing homework and my mom is right there

I know this is out of context but I would really like to see "it" play FNAF or any horror game. I really hate the game but I wanna see if it's possible or possibly play with another AI that is just the same as it is like CS:GO in a small map 1v1 something like that. Of course it will be difficult to implement but this is just a suggestion and it really impresses and astounds me very much.

No fundamental reason; I talk about this a bit in the paper. I'll probably try it after this next round of games with the original algorithm. RC Pro-Am is a good idea, because bad driving is pretty funny.

Make more, this is really enjoyable to watch, and not many people make them. I got it myself, and it's learning to play mario NES right now, and I really suck at it, so I wonder how it'll end up. I have a question: Can it get good enough to perform arbitrary code within the game to hack it's self infinite points, by performing certain actions at certain times? Of course after many weeks.

That was great! I was laughing at your renditions of the AI, and the AI's performance on the last game.

Patiently waiting for douchetrade 3.2

Sure, anything with an emulator would work in principle, but someone would have to do the work to hook it up. There are some things specific to NES (like knowing the number of buttons and the size of RAM) but they would generalize easily. The simpler the console, the better, though.

Oh my god that ending. XD

Rush'n Attack was brilliant :) also the dude saw the future of the cold war ending and then the future of it swinging back

You are hilarious.

laughing so hard at the idea of a human constantly opening the menu to see if they got the triforce yet

lol i love these videos man! thanks for the laughs:)

ML has come a long way! -Viewer in 2021

It's cool like you're still active in the comment section of a 2 year old video LOL :D

I like how aggressive Playfun/Learnfun gets as it goes on.

so curious if this could even be semi-functional on ninja-gaiden

These are so entertaining to watch. And your comments are hilarious lmao

Holy shit this is the best! ^^ I am dying of laughter seeing that 'AI' stab all those ARs. (Artificial Russian) Very impressive, and I hope we'll get to see some more videos of your progress soon! :)

why is this so funny? I couldn't control my laughter at some points! And nice programming skills.

So if you leave the program learn fun going for a really long time, can play fun master a game?

It gets angry when it loses, that's honestly just too awesome.

You're commentary is honestly hilarious. Got me laughing pretty hard. 10/10

Keep making playfun videos!

Please do more of this videos! I am studying computer science and I also wants to get on this field of learning machines etc. It is very cool what you did there...great job

This is a amazing serie! I'm laughing too much... ;D Keep up!
