TD-MPC Explained, With Alexander Soare (Part 2 of 2)

In this video I explain how we train the neural networks of TD-MPC. TD-MPC paper: https://arxiv.org/abs/2203.04955 FOWM paper (this is what's behind the implementation in the LeRobot library): https://arxiv.org/abs/2310.16029 LeRobot code: https://github.com/huggingface/lerobo... Many thanks to Nicklas Hansen et. al. for publishing their research and open sourcing their code.
