On: OpenAI Five Benchmark

How do 5 DotA players coordinate? They share information via voice?

How does a deep learning algorithm coordinate between 5 heros? I assume it's not 5 bots communicating over some channel but one bot acting on 5 heros?

[supermdguy → keepingscore]

Surprisingly, it's 5 completely separate bots:

"OpenAI Five does not contain an explicit communication channel between the heroes’ neural networks. Teamwork is controlled by a hyperparameter we dubbed “team spirit”"

[sakarisson → supermdguy]

So the bots do not communicate directly?

[Anderkent → sakarisson]

The bots presumably "learned" that the other heroes act the way that the bot would have acted were they in that position (i.e. all my allies run the same algorithm, so I can predict what they would do)

[sullyj3 → sakarisson]

That seems like a pretty serious disadvantage
