摘要:

本文讨论了从汽车加速度传感器的信号估计驾驶员困倦的学习任务。由于即使驾驶员自己也不能及时地感知他们自己的困倦,除非他们使用繁重的侵入式传感器,因此获得每个时间戳的标记训练数据不是现实的目标。为了解决这一问题,我们将任务定义为弱监督学习。我们只需要为每个完整的行程添加标签,而不是独立地为每个时间戳添加标签。通过假设驾驶员困倦的某些方面会随着时间的推移而增加,我们制定了一个算法,可以从这种弱标记数据中学习。我们推导出一个可扩展的随机优化方法作为实现算法的一种方式。在真实驾驶数据集上的数值实验表明了该算法相对于基线方法的优势。

英文摘要:

This paper addresses the learning task of estimating driver drowsiness from the signals of car acceleration sensors. Since even drivers themselves cannot perceive their own drowsiness in a timely manner unless they use burdensome invasive sensors, obtaining labeled training data for each timestamp is not a realistic goal. To deal with this difficulty, we formulate the task as a weakly supervised learning. We only need to add labels for each complete trip, not for every timestamp independently. By assuming that some aspects of driver drowsiness increase over time due to tiredness, we formulate an algorithm that can learn from such weakly labeled data. We derive a scalable stochastic optimization method as a way of implementing the algorithm. Numerical experiments on real driving datasets demonstrate the advantages of our algorithm against baseline methods.
