Reinforcement learning has achieved significant milestones, particularly in games like Go and Dota, and continues to enhance large language models. While traditional algorithms like proximal policy optimization (PPO) are effective, they require extensive tuning, which limits their applicability to new domains. Dreamer revolutionizes this field by employing a general approach that utilizes a fixed set of hyperparameters. It develops a world model, allowing agents to predict the outcomes of actions and choose the best paths forward. This innovation enables better performance in various tasks and reduces the computational burden of reinforcement learning applications.
