RL²: Fast reinforcement learning via slow reinforcement learning
OpenAI has published a series of research papers detailing advancements in reinforcement learning (RL). These include achieving superhuman performance in the game Dota 2 using large-scale deep RL, developing benchmarks for safe exploration in RL environments, and quantifying generalization capabilities with a new environment called CoinRun. The research also explores novel methods like Random Network Distillation for curiosity-driven exploration, Evolved Policy Gradients for faster learning on new tasks, and variance reduction techniques for policy gradients. Additionally, OpenAI is investigating policy representations in multiagent systems and the theoretical equivalence between policy gradients and soft Q-learning. AI
