In a new paper Bigger, Better, Faster: Human-level Atari with human-level efficiency, a research team from Google DeepMind, Mila and Universite de Montreal presents a value-based RL agent, which they call faster, better, faster (BBF), that achieves super-human performance on the Atari 100K benchmark on single GPU.
In the new paper Human-level Atari 200x Faster, a DeepMind research team applies a set of diverse strategies to Agent57, with their resulting MEME (Efficient Memory-based Exploration) agent surpassing the human baseline on all 57 Atari games in just 390 million frames — two orders of magnitude faster than Agent57.
A research team from DeepMind and Amii extends the emphatic method to multi-step deep reinforcement learning (RL) targets, and demonstrates that combining emphatic trace with deep neural networks can improve performance on classic Atari video games.
Agent57 is the first deep reinforcement learning (RL) agent to top human baseline scores on all games in the Atari57 test set.
Model-free reinforcement learning can be used to learn effective strategies for complex tasks such as Atari games, but it usually requires a large amount of interaction, which adds significant time and cost.
