摘要:

仿真是验证自动驾驶汽车安全性的一个有吸引力的选择。生成对抗模仿学习(GAIL)最近被证明可以学习代表性的人类驾驶员模型。这些人类驾驶员模型是通过在单智能体环境中的训练来学习的,但它们很难推广到多智能体驾驶场景。我们认为这些困难的出现是因为在训练和测试时的观察是从不同的分布中采样的。这种差异使得这种模型不适合模拟驾驶场景,其中多个代理必须在长时间范围内进行逼真的交互。我们扩展GAIL,以解决这些缺点,通过一个参数共享的方法接地课程学习。与单代理GAIL政策相比,我们的PS-GAIL方法产生的政策证明优越的互动稳定在多代理设置和捕捉人类司机的紧急行为。

英文摘要:

Simulation is an appealing option for validating the safety of autonomous vehicles. Generative Adversarial Imitation Learning (GAIL) has recently been shown to learn representative human driver models. These human driver models were learned through training in single-agent environments, but they have difficulty in generalizing to multi-agent driving scenarios. We argue these difficulties arise because observations at training and test time are sampled from different distributions. This difference makes such models unsuitable for the simulation of driving scenes, where multiple agents must interact realistically over long time horizons. We extend GAIL to address these shortcomings through a parameter-sharing approach grounded in curriculum learning. Compared with single-agent GAIL policies, policies generated by our PS-GAIL method prove superior at interacting stably in a multi-agent setting and capturing the emergent behavior of human drivers.
