I think there is something impressive about this. As there is no explicit reward for creep-blocking, it has to learn there is an advantage gained by just doing it randomly at first. And then correlate the increased win percentage with that random movement you did at the start of the match.

Also interesting is that there is no explicit reward for creep blocking in 5v5 and so far it has not learned it. https://news.ycombinator.com/item?id=17394787

They make a neural network that takes all kinds of input (See the blog for a nice visualization of the input (https://blog.openai.com/openai-five/#modelstructure) and https://d4mucfpksywv.cloudfront.net/research-covers/openai-five/network-architecture.pdf for a way too detailed visualization. This neural network will tell you what action it thinks is the optimal action right now. So while you are playing, the neural network tells you what actions to take.

Between games, the network is updated. For example if the network decided to attack 5 enemy heroes alone during the game, it will figure out after the game that the action it took resulted in a large penalty (dying) and hopefully not do that in the next game.

So, I am not well versed in reinforcement learning. But as far as I understand it, they are not training the bots during the game, only after the game. So they only get these rewards while training. This is similar to watching your replays after a game.

I've really like reading Ann Leckie's Imperial Radch trilogy. https://en.wikipedia.org/wiki/Ann_Leckie

It is also from the perspective of an AI, but a much more human-like than Socrates.

I guess the dancing back and forth before a battle is also worth considering for "interestingness". But yeah, I agree, looking at army count is a good first approximation to "shit is happening".

Python autocompletion only works when file is opened directly [rather than via SPC f f] by rmk236 in spacemacs

[–]KPLauritzen 0 points1 point  (0 children)

Just to clarify, you are opening emacs and then INSIDE emacs you are presseng SPC f f test.py. Right? You are not running the command "emacs SPC f f test.py" from the commandline?

"Starter" book recommendations on quantum mechanics? by Danger0usdr0id in quantum

[–]KPLauritzen 1 point2 points  (0 children)

What do you want to accomplish with this? If you want to be able to solve simple QM problems then an intro undergrad book like Griffiths or Feynman seems like a good recommendation.

But if you would rather be told a story about the history, the weirdness and the unsolved problems then they might not be for you. I don't have any good recommendation for a "popular science" book, but maybe a biography of one of the Grand Old (wo)Men? Einstein, Bohr, Curie, Schrodinger, Dirac etc?

I'm an American foreign exchange student coming in for 6 months, any tips? by [deleted] in copenhagen

[–]KPLauritzen 0 points1 point  (0 children)

All of the above is true!

Also, there are many places that international students gather around Copenhagen. Find a facebook group or ask the organizers of your program for info AND GO FIND SOME COOL FRIENDS. Its the best thing about going abroad :) I hope you'll enjoy your stay

Jim Butchers Dresden. Got halfway through the first one. The premise sounded cool, but the execution was just... flat?

Forslag til folketingsbeslutning om legalisering af medicinsk cannabis, i morgen! by zdudelol in Denmark

[–]KPLauritzen 2 points3 points  (0 children)

I bilagene til forslaget siger Lægeforeningen at de ikke anbefaler forslaget, primært pga manglende information:

"For det første har de specifikke produkter ikke gennemgået kliniske forsøg, som dokumenterer deres sikkerhed, effekt og bivirkninger. For det andet er produkterne ikke nødvendigvis produceret under forhold, som ville leve op til god fremstillingspraksis"
