arXiv – CS AI|Zhexi Lian, Haoran Wang, Xuerun Yan, Weimeng Lin, Xianhong Zhang, Yongyu Chen, Jia Hu|
🤖AI Summary
Researchers propose PaIR-Drive, a new parallel framework that combines imitation learning and reinforcement learning for autonomous driving, achieving 91.2 PDMS performance on NAVSIMv1 benchmark. The approach addresses limitations of sequential fine-tuning by running IL and RL in parallel branches, enabling better performance than existing methods.
Key Takeaways
- →PaIR-Drive separates imitation learning and reinforcement learning into parallel branches to avoid policy drift issues in sequential training.
- →The framework achieved competitive performance of 91.2 PDMS and 87.9 EPDMS on NAVSIM benchmarks, outperforming existing RL fine-tuning methods.
- →A tree-structured trajectory neural sampler enhances exploration capability in the reinforcement learning branch.
- →The approach can correct suboptimal human driving behaviors and generate high-quality trajectories.
- →The parallel design eliminates the need to retrain RL components when applying new imitation learning policies.
