Wait… the big news here is steam.tv. I heard the rumors but didn't know it was up?! (it seems to work only for their own event at this time tho.)
They announced it a couple of days ago: http://blog.dota2.com/2018/08/the-main-event-with-new-steam-... It still have limitations and bugs, yesterday it just wouldn't load for me, but it works now, and you are unable to watch yesterdays content.
The UI is very wonky, definitely looks like it was rushed last minute to release for TI. That "Watch with friends" button is pretty messed up if you're logged in. Also if you're logged in and "close" the stream tab, I don't see any way to get back to it. Definitely a work in progress.
for a bot, they sure are doing pretty well versus the top 5% of the skilled dota players, assuming that only the top players around the world can enter the main international event.
It’s 0.05%. But also the game OpenAI plays is very limited. It’s a very small game compare to the real Dota. They just got rid of a small limitation of having 5 invulnerable couriers and already being punished hard (since their push timing being delayed). And Dota is much more complicated than just team fighting and death ball.

I find it amusing & ironic that they're pursuing games of efficiently & strategically killing enemies as examples of their successful progress. ;-)
This 200ms restriction seems really slow, but it isn’t. It feels extremely fast, to the point where some heroes and tactics used by humans are useless or impossible. For example, one of the humans played a hero called Axe. It was literally impossible to land one of his skills because it takes 400ms to use it. I’ve seen a lot of professional Dota but I’ve never seen Axe calls being dodged so perfectly and consistently…
200ms is a good measurement on how fast a skilled human can react with a single keypress like activating BKB or phase shift. Players like VP.Noone can be seen doing such reactionary moves even faster than 200ms. Double clicks will already take longer due to slow fingers, which would be the self eul's to avoid axe's call. The moves where eul's was used on axe or blink dagger to escape, well those require players to al…
This made me think that on top of having a 200ms in actions perhaps the AI can use an action queue where each action will have a delay of 50 ms. This will be a good way to simulate the human latency in using fingers to send the keystrokes. So, if a the DP want to use eul, she will end up taking 200 (base latency) + 50 (first click) + 50 (2nd click) = 300 ms. Still would be able to dodge but now it is much more competitive.

Except that the amusement and irony would cease to exist once you have some idea of what's happening behind the scenes.
The AI doesn't know it's "killing enemies". For it, it's just something that results in the increase of a numerical reward signal.
Reaction time seems to be a lot more complicated than just 200ms flat. There were a lot of superhuman reactions that game which really made it difficult for humans to start a fight. At the same time though, increasing much more than 200ms might give a big advantage to humans in other situations. It will be interesting to see if they can find a better way to model it. All in all I am very impressed by the AI. So many…
The human would probably be able to blink/cancel if they were expecting it and therefore able to focus on a single thing prior to an event. The bot can focus on everything simultaneously and doesn't really need to expect anything. It gets a signal, it responds within 200ms, no problem. You could program that analytically. So I would say the superhuman-ness isn't in the number of actions taken, or in the response dela…
One thing to keep in mind is that humans have to process the game from the image on the screen and input through a mouse and keyboard. We have to move the mouse to react to things. The computer is super-human in part because it doesn't have to do these things. It will be interesting to see if they can translate their learnings to bots that react from the image on the screen rather than the API.
> his team isn't the strongest (they placed 17-18th during this TI) Oh, is that all :P. Assuming a 2x buffer for players who are good but not competitive, there are maybe 200 humans in the world who are better at DotA. If mastery is 1 in 10,000, these people are masters.
No, there are way more than 200 players better than Pain, all due respect to them. That’s clear by looking at leaderboards. But team dynamics and synergy in this game matter so much that they are definitely in the top 20 of teams regardless of their individual skill. Seeing OpenAI do so well against this team impressed the hell out of me.
The way TI is structured they invite one team from South America. So Pain is likely not in top 20, but still a very good team.
