基于学习的自动驾驶教练系统在复杂操作任务(如高性能驾驶)中,因仅依赖局部上下文推理,难以适应学生长期学习过程和重复师生交互的累积影响。本文提出一种基于模仿学习的自适应教学模型,配备专用的时间推理模块,在低数据条件下可利用历史交互信息进行推断。为弥补有限的交互训练数据,结合教学过程的重复性,模型采用最近邻检索与交叉注意力先验,仅聚焦语义相似的历史交互片段,并通过编码器-解码器结构实现并行教学。我们在两个数据集上验证:(i) 基于Waymo Open Motion Dataset构建的新型半合成闭环纵向师生交互数据集;(ii) 小规模真实世界自然情境赛车教练数据集。结果表明,引入最近邻检索与交叉注意力先验的自适应模型,在多个指标上持续优于非自适应基线及不同先验/时间融合机制的自适应模型。

原文摘要 · Abstract (English)

Learning-based automated coaching systems for complex motor tasks such as high-performance driving remain limited in the ability to be adaptive by their reliance only on local, context-dependent reasoning, failing to account for the long-term temporal nature of student learning and the cumulative impact of repeated teacher-student interactions. In this paper, we propose an imitation learning based computational model for adaptive teaching with a dedicated temporal reasoning module that can reason over the interaction history under low-data regimes. To compensate for limited amounts of interactive training data, and based on the repetitive nature of the teaching process, the model relies on a nearest neighbor retrieval and cross attention prior, reasoning only on a narrowed-down set of semantically similar past interactions with an encoder-decoder based concurrent teaching model. We validate our approach with (i) a novel semi-synthetic closed-loop longitudinal student-teacher interaction dataset based on Waymo Open Motion Dataset and (ii) a small-scale real-world naturalistic simulator race coaching dataset. Our results reveal the consistent advantage of our adaptive teaching model with the nearest neighbor retrieval and cross-attention prior over a non-adaptive baseline as well as a suite of adaptive models that differ in their choice of priors and temporal fusion mechanisms.
