Reinforcement Learning in Strategy-Based and Atari Games: A Review of Google DeepMinds Innovations
It addresses the problem of developing adaptable AI for gaming, serving as a benchmark for AI research, but is incremental as a review of existing models.
This paper reviews Google DeepMind's reinforcement learning innovations, such as AlphaGo, AlphaGo Zero, and MuZero, which tackled mastering games like Go and Atari, with results including surpassing human players and achieving adaptability across multiple games.
Reinforcement Learning (RL) has been widely used in many applications, particularly in gaming, which serves as an excellent training ground for AI models. Google DeepMind has pioneered innovations in this field, employing reinforcement learning algorithms, including model-based, model-free, and deep Q-network approaches, to create advanced AI models such as AlphaGo, AlphaGo Zero, and MuZero. AlphaGo, the initial model, integrates supervised learning and reinforcement learning to master the game of Go, surpassing professional human players. AlphaGo Zero refines this approach by eliminating reliance on human gameplay data, instead utilizing self-play for enhanced learning efficiency. MuZero further extends these advancements by learning the underlying dynamics of game environments without explicit knowledge of the rules, achieving adaptability across various games, including complex Atari games. This paper reviews the significance of reinforcement learning applications in Atari and strategy-based games, analyzing these three models, their key innovations, training processes, challenges encountered, and improvements made. Additionally, we discuss advancements in the field of gaming, including MiniZero and multi-agent models, highlighting future directions and emerging AI models from Google DeepMind.
