AlphaStar: Grandmaster level in StarCraft II using multi-agent reinforcement learning
  • AI agent AlphaStar has been trained, using novel techniques, to be better than 99.8% Starcraft II players, and achieve Grandmaster level for all 3 races in the game.
  • The AI uses a camera interface, it’s limited to receiving similar input information, and playing at a similar speed to human players, and plays anonymously on
  • One of the key innovations was using a League self-play system, which involved flaw-exposing agents alongside win-oriented agents.
  • Other techniques included neural networks, multi-agent learning and imitation learning.
  • The study helped improve those methods by adapting them to a complex, dynamic environment, contributing to the safety and robustness of AI systems in general.
