Coarse-to-Fine Q-attention: Efficient Learning for Visual Robotic Manipulation via Discretisation

1 code implementation CVPR 2022 Stephen James, Kentaro Wada, Tristan Laidlow, Andrew J. Davison

We present a coarse-to-fine discretisation method that enables the use of discrete reinforcement learning approaches in place of unstable and data-inefficient actor-critic methods in continuous robotics domains.
