The use of embeddings in OpenAI Five
&gt; I think it is amazing that one relatively simple mathematical construct can produce such a complicated behavior.<p>No complicated behavior was produced.<p>&gt; Or, I don’t know, maybe it says something about the complexity of Dota 2 game?<p>Dota 2 game was not played. A tiny subset of the game was attempted. Since people seem to be just buying whatever OpenAI propaganda sells them, let me be specific: only 18 heroes are in the game. The combinatorics explode when you go from 18 to 110. Go on a 5x5 board is a joke compared to 19x19 Go. This is not hard to understand.<p>&gt; Do short term tactics combined with fast reaction time beat long-term strategy?<p>In a game designed for humans, perhaps yes, because the game wouldn&#x27;t be tested against extremely fast reaction times. The game was meant to be a strategic game for humans. Just because OpenAI Five appears to play Dota 2 (still doesn&#x27;t beat any serious players though) doesn&#x27;t imply anything fundamental about tactics beating strategy.
