AlphaStar StarCraft II — main technical innovations.

hard

Answer

$Vinyals et al. 2019.$
$(1) LSTM policy + transformer over units.$
$(2) SL from replays \to RL via league play.$
$(3) Auto-regressive action distribution over unit + action + coordinates.$
$(4) Distributed at scale (thousands of parallel games).$
$(5) League: Main / Main Exploiter / League Exploiter roles prevent strategy cycling.$
$Grandmaster level; imperfect information + real-time + long horizon.$

Check yourself — multiple choice

Random
LSTM + transformer over units + SL from replays → RL league play (Main / Main Exploiter / League Exploiter) + auto-regressive action + distributed scale; Grandmaster level
Same as AlphaGo
Not real

AlphaStar: LSTM + transformer + SL→league RL; Grandmaster StarCraft II.
