First off, hello there, I'm deadbabies, and I will be taking over as /sci/ moderator. Rules will remain the same. Please use the report function if you see posts that violate the rules, but also do not abuse it.

I have officially expanded the scope of /sci/ a bit. You may discuss Science, Technology, Engineering, and Mathematics here now. No science is discriminated against as long as it's of the peer-reviewed variety. If someone wants to discuss Anthropology or Social Science, by all means, let them. If you do not like it, just don't post in the thread.

The IRC channel #/sci/ is now (finally) re-registered and I am running as operator on here. Feel free to stop by and say hi. I do leave my computer idling on IRC, so check back or leave me a message if you have any ideas, suggestions, or just want to tell me off. You can get onto #/sci/ by joining the server irc.7chan.org at port 6667. You can also use SSL at port 6697 but you will have to set your client to accept invalid certificates.

ADDITIONALLY and IMPORTANTLY I have had several requests on IRC regarding the old Ebook FTP that we used to have. Unfortunately, the mod who ran it entered the military and no longer runs or maintains it. I have no plans to make another one, but if one of you guys would like to, by all means advertise here.

That being said, I'm just going to leave this link here:

http://ebookee.org/index.php?tag=7

You may find what you seek here.

I will be unstickying the old ebook/source articles thread. Please post any new ebooks/source articles here, and feel free to post any working links from the old thread there; I will eventually be deleting it.
Message too long. Click here to view the full text.

I want to learn mathematics. The next year I'll start a career of Pure Mathematics and I have a lot of years (5 aprox.) of neet. I'm looking for books to learn the topics about Mathematics in High School, alegbra and trigonometry, what else? If you can give me reference, please.

Machine learning for gaming AI? Anonymous 16/02/10(Wed)13:52 No. 16279 ID: 716d81 [Reply]

Hello /sci/!

Let's say that I want to create an AI for a simple board game, maybe chinese checkers. So I record multiple games with 2 to 6 players.

So can anyone please tell me if there's
some program that can simply read the database and construct a gaming AI from it?

What you'd want to do instead is create an agent that understands the allowed moves. Use multiple agents to play against each other. Incentivize the agents by assigning weights to different conditions. Things like -1 point for losing a piece, +1 for taking another player's piece, -100 for losing the game, +100 for winning. Then let the agents play each other a couple hundred thousand times and store the patterns.

The system would then follow paths in a decision tree for each state of the game to the next state, following the higher point paths.

What you've described (The recording and analyzing would be a very minor part, and observing enough games to program an AI would be difficult if they were real games.)

Other options include incentivizing other goals, like control of the middle of the board, or attacking the player with the most pieces. This could lead to other strategies that the system could then utilize.

Look up reinforcement learning. But for Chinese checkers ab pruning should suffice

  I'm not too educated in physics and its principles and theories, but does anyone think that some of the theories of the Standard Model (e.g. Heisenberg Uncertainty Principle, Fermat's Principle) could be ~debunked~ or proven to be false? Is the Standard Model close to perfect? How close is what we know now to fully understanding all of physics?

I'm basically at the same tier you are or even dumber, but one thing I know is in neutrinos. The SM predicts that they are massless, but from observations they have to have mass. Because they oscillate, they need to have different mass eigenstates to allow for different wavelengths to interfere or something.

Not any time soon.

Not even close.

I will say this: Debunking the standard model is unlikely, however it is without doubt incomplete. It is a very interesting area to look into and there is plenty of current reasearch in this direction. You could go for a theoretical side of things which would be quantum field theory or a experimental side which looks at incompatible data with the model. Indeed the standard model is considered the most complete and accurate success of physics, however it is by no means close to enough.

Best STEM degree?

Best degree is the one you enjoy. If you enjoy Chemistry but not Computers, Computer Science would be a poor choice.

You have to define what "Best" means.

If it's only money, petroleum engineers are paid well. Computer Science will get you a job, but you'll have to put in a lot of work to stand out. Maths is not so good unless you plan to go into academia, but can be a nice add-on as a second bachelors.

petroleum engineers will either make a shit ton of money or they'll be jobless. It really depends on the market and if there are any jobs available.

I'm guessing HVAC repair would be the best STEM major for you. Really though, study what you want to learn about. Look at your college's 300 (or 3000) level classes and above. Decide which ones you want to do. Find twenty of those in the same major and that's your major. If you can't find a job after you graduate sign up at your local state U for a master's certificate in something you can get a job at. (not master's degree, certificates are 5 -6 classes, about a year / tear and a half of night school)

I'm a noob about computers and going to do college of Computer Engineering. I don't know even how to start learning. Can somebody give a tip?

It is Easy
There is 4 main components that is essential for your PC
1st A processor(This is what makes your computer run, Without it the computer will probably not function at all)
2nd A Video Card(however some processors have built in video cards in them either called intergrated or APU's)
3rd A Power Supply(Obviously)
4th A Motherboard(This is where all the components connect and unite together)
Start From Learning that and then gradually learn it from sites that can help you such as tomshardware and techguru.

The easiest way to start any entirely new field is to study its history and development, and read about the peaple who made it happen. Then you have a grounding and orientation for your technical studies.

Science Fiction, but still fun.

Actually there was important point brought up about the micro-ARC power source in the first Avengers movie: Loki is unable to use his tesseract-based mindwarp staff on Tony. Tony's "new element" is tesseract-like technology. I suspect he's discovered the molecules that the stones of power are made from, but not yet achieved their level of energy concentration.

As for the second movie's retconnning that the staff is actually powered the mind stone... I guess the only way to make sense of it is that all the stones have a technological similarity.

>Loki is unable to use his tesseract-based mindwarp staff on Tony. Tony's "new element" is tesseract-like technology.

It was because Loki was poking Tony in the Arc, not his actual body (notice the audible 'chink' when they connect). If Loki had been two inches to the right he would have succeeded.
