Federated Transfer Reinforcement Learning for Autonomous Driving

no code implementations14 Oct 2019 Xinle Liang, Yang Liu, Tianjian Chen, Ming Liu, Qiang Yang

Reinforcement learning (RL) is widely used in autonomous driving tasks and training RL models typically involves in a multi-step process: pre-training RL models on simulators, uploading the pre-trained model to real-life robots, and fine-tuning the weight parameters on robot vehicles.
