Extremely important potentially world-changing idea: Judo/BJJ Machine Learning

Anyone who has followed MMA or Brazilian Jiu-Jitsu now knows that often the best combat techniques are not readily apparent -- in fact some are downright ridiculous looking and counterintuitive. A good example that comes to mind is "inverted guard". It involves raising your legs over your head as if you were trying to suck your own dick and somehow using that to your advantage against your opponent. I had it done to me at a gym recently and it completely boggled my mind how easy it was for him to put me in the rear naked choke from that initially awkward position.


Then for some reason my mind wandered to computers and their abilities in human games. We know that Brazilian Jiu-Jitsu is a special martial art in that it is extremely analagous to chess (no really, I'm not trying to sound flowery; this is a well-documented and true analogy, as people who do both BJJ and chess will understand). We also know that COMPUTERS CAN BEAT HUMANS AT CHESS.


So I was wondering "maybe we can invent a robot with same weight and strength and test its intellect against the BJJ champion". But that's too difficult b/c of the material required. So then I thought, "what are the uses for keeping it all software, no hardware?" A simulation, of course!


Now the question is: How much more "weird shit" is there to discover? Maybe martial arts and MMA have evolved long enough for humans to basically discovered most of the best techniques to use -- triangle, kimura, armbar, etc. Then again, maybe not (inverted guard is probably rather recent)! So in order to discover these new techniques, should we just roll around and discover them ourselves? Should we let the masters discover it and have it trickle down to us? OR, the third option: by MACHING LEARNING.


This is what I propose:


1. Program in the physics, kinematics, rules of the game, and the human body as accurately as possible, down to joints at least as small as the wrist. This is probably the hardest part, and we will have to tweak it until it looks like real humanoid BJJ/Judo.

2. Create a "starting" artificial intelligence agent. This agent should have a lot of pre-programmed techniques (all known techniques) and should preferrably already be as good as a black belt in BJJ/Judo.

3. The game is basically the agents running "minimax" algorithm on each other to see what is the most likely way to "finish/checkmate" (submit) the opponent.

4. Run a ton of games, 1on1, with varying weights, reaches, and reaction times, and use GENETIC ALGORITHMS to select only the most intelligent players

5. Run it for a very long time, tweaking if necessary

6. Observe the playing style of the finished product and see if it is different from regular human black belt players!

Girlfriend raped dream

I was out with a girl and we had to go to the bathroom. I noticed that the girl's bathroom had a dude in a hazmat mask pretending to be a zombie, but for some reason I was okay with it and thought it was totally normal. So she goes into the bathroom but the "zombie" follows her to the stall... now that is not normal.


Unfortunately as I am about to go save her I am simultaneously attacked by two men. Fortunately I am able to quickly incapacitate one with some non-judo such as knees, but he keeps getting back up so I resolve that I have to kill him. At this point my other attacker, for whatever reason, became unhostile to me, so I explain to my other attacker that "I am not trained to kill" so it takes me a while to crank his neck until he dies.


Then I go in to save my girl in the stall but it's too late; she's already been raped. I see that the guy has left behind a one-dollar bill (implying she is a one-dollar ho) and a note saying "Dear Max, I had fun raping her" etc. So then I find the guy hiding in the stall and start beating him to pieces intending to kill him, only to realize later that I am actually beating on a stuffed animal which is unkillable, much to my dismay and anger. He must have been raping her through a proxy stuffed animal or something.




I ask her why she didn't cry out for help but she says she can't answer. This pisses me off and I tell her she is like one of those stereotypical movie or video game characters that can't reveal plot details until later on, but she tells me she really has her own good reason for not telling me. So I accept that because I love and trust her. Then I realize she has somehow turned into this weird-looking white girl who is a head taller than me and has black cheeks that are puffed out, and weird lips. I still love her, but I remark to her that she has grown much taller in the past hour.


Anyway it's time to escape this hotel room before the bad guys figure out we didn't die. We have been constantly on the run from bad guys with limited gas in our car and limited cash, staying periodically in hotels, so it's time to leave (by the way I LOVE this thrilling recurring dream, perhaps even more than the zombie apocalypse dream). So we jump out the window but the bad guys hear us and begin to chase us. I press the "unlock" button on my car key. A car begins to flash its lights, but I know it's not mine and is instead a decoy trap set by the bad guys. After jumping over a bad guy car who tried to run me over, and running a while longer, I finally find my car. Alas, we were not finished packing from yesterday and there's a giant swivel chair behind my car and the trunk is open. No problem, I throw the chair in the trunk and start the car. But my girlfriend heads off in a different direction and jumps into a completely different car, which works to my surprise. But I want us both in my car so I motion for her to jump into my car. So here I am driving my car with all its doors open trying to pick up my girlfriend who is on the run from the bad guys trying to run her over. Quite a sight.


Finally she is able to hop in my car, but at this point my car became a bus, and the bus driver said we were at max capacity. I wasn't about to let a stupid bus driver stop us from escaping the bad guys! "No problem," I said, "Just keep stalling him until I drive us to the bridge, and then we won't be able to turn back anyway." So I floor the gas pedal, but suddenly the drawbridge in front of us raises, thereby trapping us! I had the brief idea to turn around and go the other direction but realized that we were on a boat! We were therefore trapped with the bad guys on a medium-sized boat, due for another day of trying to kill/avoid bad guys...



Before I awaken, I remark that my subconscious is a brilliant story writer for putting me in this inescapable situation. In reality, it's just because I was stupid enough in my dream state to accept that driving a bus onto a boat is normal, and that busses usually have two drivers.

Evil Sam Dream

Part 1:

I am in some sort of obstacle course marathon with a friend. We encounter some cuts of cooked pork (one of the many food resources scattered throughout the park to prevent starvation), but it is completely unprotected from the elements, and some ants are crawling on it. "You know, I'm really glad that it's just ants, because if it were worms I'd totally not eat this," I tell my obstacle course buddy. Then a strange-looking pincer bug scampers across one of the meats. I cringe and lose all appetite. My buddy calls me a pansy.

Part 2:

At some point during what appeared to be an innocent conversation with Sam and his accomplice, a white car spontaneously appeared out of nowhere and crashed into two innocent people in the room, sending them flying. They were not the target -- I was. The car had been headed for me but they were in the way, and they slowed the momentum of the car just enough for me to sidestep it.

At this point Sam and his accomplice both haughtily revealed that they had plans to take over the world. Apparently the first step of this plan was to kill me.

The car kept running people over, trying to get to me. I kept reassuring myself, "Ahn is driving the car so of course he will not run me over," but unfortunately he kept trying to run me over.

I realized that if I took out the two masterminds, Ahn would stop, so I started with Sam's accomplice (who had now morphed into an exact clone of Sam) and osoto-gari'd* him towards the ground while driving his head into a wall. This banged him up enough to knock him unconscious. I did the same thing to Real Sam, banged his head up pretty good against the wall -- but he remained conscious. He grabbed my shoulders, looked me straight in the eye, and said something cheesy like "I am not so easily defeated." The end.

*osoto-gari: A basic judo takedown involving an outer leg reap.

hot chick, drug experiments, and judo dream

RAW TEXT (short version): Took pix Everyone likes me Into society room hit on chick kiss good results. I leave. Days later dream breathe/run to same room sign forms for society no time commitment. Days later drink weird juice fan very cold. I dance but they say "wut u doin?" Not party. Tests. Effects subside but I know movie ends w everyone dying. Oh before that, while fan cold Mr Grantham goes out of room and doesn't let me out. Concerned admin. Ok so he's gonna make us drink another. I slowly then quietly run away. run a lot till I in field near dorm but he appear from other side We judo (he Han now) but he say if I beat him at judo he'll curse/kill me I'm like wtf.


DETAILED RECOLLECTIONS (long version):

I was with my family, and we were leaving this place to go home. Parents and sister had gone ahead, but I had taken a detour into one of many rooms in this building. It is some sort of long but informal dining room, with long tables.

I stride confidently into the room and there's a lot of dudes and a couple of chicks. They are just drinking and having a good time, and they remind me of frat/sorority people. Though no one knows me, everyone welcomes me because I am the new random guy who walked in. Somehow I also strike up a fun conversation with the one hot chick.

There is one adult about 30 years old. He takes some pictures of us. I pose with the hot chick and kiss her a bit. She playfully pretends to reject me but actually likes it.

I say gotta go and run back to rejoin my family and we leave. I realize no one has my phone number or even name. Oh well.

---stuff happens here. I think maybe I even awaken for a bit, then fall back asleep.---

I am jogging back to the dining room place (which I now know to be in UC Berkeley), because I want to get a chance to hang out with those fun people again. I arrive at the sign-up headquarters building, which is empty. The only person in the building is the 30-yr-old cameraman I saw earlier. He tells me he is the head of the organization of these people. I ask what the "time commitments" are. He tells me there are no mandatory tasks, chores, or volunteer activities, or any sort of "time commitment" other than having fun -- no strings attached other than an $80 payment per year for booze and such. So I sign up.

Next I walk into another dining hall style room. The people I met earlier are all there. We start drinking a bit. I also drink some spiked punch.

Minutes later I start to realize the air coming from the fan is very, very cold relative to the rest of the room. Since it is a regular fan with no cooling device I grow suspicious and ask people what is going on. They don't seem to care. Everyone is just sitting or talking quietly; no one is partying.

To try to relieve the tension I get up and dance in the middle of a circle. But they look at me like "what are you doing?" and it's not because of my bad dancing. I realize it is because we're not here to party. We are drinking strange drugs as an experiment for the 30-yr-old dude. Everyone is sitting around idly or talking quietly, looking serious. No smiles. No laughter. I only just realized.

I try to exit the room, but the 30-yr-old dude -- who is now my band teacher Mr. Grantham -- beats me to the door, exits the room and locks the door so I can't get out. I rattle the door handle thinking that he is not evil and will let me leave, but he just glares at me. I look outside the clear windows walls and he is talking to an investigator, apparently assuring him that nothing strange is going on inside the room.

The fan is still unnaturally cold. I know that the coldness is part of a hallucination, an effect of the drug.

The effects are subsiding but I know this dream will end with everyone dying, including me if I don't act soon. The 30-yr-old -- who is now my former Sound Art teacher -- walks back into the room and prepares a bubbly, pinkish liquid in a pot. He begins to offer the liquid to each person, all of whom voluntarily walk up and drink it. There's no way I'm going to subject myself to another, possibly deadly drug. Yet I know refusal is unacceptable and will be punished. So I rise and begin walking towards the exit, slowly at first to not appear suspicious, before breaking into a full-out dream-sprint (meaning, I am running as fast as I can as though underwater).

I successfully escape the room and run up some streets. A car rounds a corner and almost hits me. The man is still chasing me.

Suddenly as I am setting foot on a field (which resembles Duke University more than UC Berkeley) the guy -- who is now the Caucasian version of my Korean Judo Master -- appears from the OPPOSITE direction from which I was running. We judo spar a bit. He warns me that if I beat him, he will curse and/or kill me. My last thought is, "now that is very uncharacteristic of Master Han -- shouldn't he be happy if I beat him, because it means he taught me well?"

parkour/judo dream

I remember towards the end of my dream that I open my backyard gate a bit and peer outside, watching the silhouette of some dude my age walking towards me. I feel that he is hostile so I start to run back and he fires a couple of shots at me.

I parkour over my backyard's tall cement fence. Since he can't parkour he has to go all the way around to get his car first, during which I hit the emergency red button on an emergency post.

A police car who received my distress call zooms by and a backpack is flung out its window into my arms. I reach into the bag; the policeman has provided me a pistol with which to defend myself.

The antagonist, who is now my friend Sid, has finally found his car and is driving towards me. I shoot at him and his accomplice directly in the head, but either I miss or they have hard heads. Then they get out of their car and run towards me. Finally I drop one of the one who is not Sid after multiple head shots. The other guy (who is also not Sid anymore) runs up to me and I do ouchi-gari on him and then try to get into an advantageous ground position to pin him.

All this time the police officer is just sitting there in his car watching the show.
