摘要:

目标检测的性能监控对于安全关键型应用至关重要,例如在变化和复杂的环境条件下运行的自动驾驶汽车。目前,使用基于单个数据集的汇总度量来评估对象检测器,该单个数据集被假定为代表所有未来部署条件。在实践中,这一假设并不成立,并且性能作为部署条件的函数而波动。为了解决这个问题,我们提出了一个内省的方法,在部署过程中的性能监测,而不需要地面实况数据。我们这样做是通过预测时,每帧的平均平均精度下降到临界阈值以下,使用检测器的内部功能。我们定量评估和证明我们的方法的能力,以降低风险,通过提高警报和检测缺席作出不正确的决定。

英文摘要:

Performance monitoring of object detection is crucial for safety-critical applications such as autonomous vehicles that operate under varying and complex environmental conditions. Currently, object detectors are evaluated using summary metrics based on a single dataset that is assumed to be representative of all future deployment conditions. In practice, this assumption does not hold, and the performance fluctuates as a function of the deployment conditions. To address this issue, we propose an introspection approach to performance monitoring during deployment without the need for ground truth data. We do so by predicting when the per-frame mean average precision drops below a critical threshold using the detector's internal features. We quantitatively evaluate and demonstrate our method's ability to reduce risk by trading off making an incorrect decision by raising the alarm and absenting from detection.
