Dreamer 4
verifiedFreedanijar.com
Research world-model agent that learns Minecraft and robotic control tasks by training in imagination purely from offline data.
What it does
Dreamer 4 is a research project (by Danijar Hafner and colleagues) presenting a scalable reinforcement-learning agent that learns inside a fast, accurate world model. By practising tasks in 'imagination', it became the first agent to obtain diamonds in Minecraft purely from offline data, and it can also simulate object interactions on robotics datasets.
