自动驾驶系统中基于搜索的场景生成中的噪声处理

Handling Noise in Search-Based Scenario Generation for Autonomous Driving Systems

National Institute of Informatics(国立情报学研究所)

Stefan Klikovits, Paolo Arcaini

摘要:

本文介绍了第一次评估的k-最近邻平均(kNN-Avg)在现实世界的案例研究。kNN-Avg是一种新的技术,可以解决噪声多目标优化(MOO)的挑战。现有的研究建议使用重复来克服噪音。相比之下,kNN-Avg近似这些重复并利用以前的执行,从而避免重新运行的成本。我们使用kNN-Avg的场景生成的一个真实世界的自动驾驶系统(ADS),并表明它是优于嘈杂的基线。此外,我们将其与重复方法和大纲指标进行比较,以确定在哪些情况下选择哪种方法。

英文摘要:

This paper presents the first evaluation of k-nearest neighbours-Averaging (kNN-Avg) on a real-world case study. kNN-Avg is a novel technique that tackles the challenges of noisy multi-objective optimisation (MOO). Existing studies suggest the use of repetition to overcome noise. In contrast, kNN-Avg approximates these repetitions and exploits previous executions, thereby avoiding the cost of re-running. We use kNN-Avg for the scenario generation of a real-world autonomous driving system (ADS) and show that it is better than the noisy baseline. Furthermore, we compare it to the repetition-method and outline indicators as to which approach to choose in which situations.
