Some results from the latest paper Tractable Large-Scale Deep Reinforcement Learning by Nima Sarang and Charalambos Poullis, on deep reinforcement learning. The code is publicly available at https://github.com/nsarang/road-extraction-rl.
TL;DR: We reformulate the problem of road extraction by training an RL agent to traverse the roads from satellite images. We introduce novel techniques for making this inherently complex problem tractable on commodity GPUs and propose a self-supervised loss and actions tailored for road extraction.
The orange lines show the ground truth and are only used during training. The first three videos are from the test dataset and the final from the training.
