论文摘要
在本文中，使用Resnet-34作为功能提取器，将基于LSTM的基于LSTM自动编码器的体系结构用于嗜睡。该问题被认为是单个受试者的异常检测。因此，只有普通的驾驶表示形式，并且可以根据网络的知识来区分嗜睡表征，从而产生更高的重建损失。在我们的研究中，通过标签分配的方法研究了正常和异常剪辑的置信度水平，以便根据不同的置信率分析了LSTM自动编码器的训练性能以及测试过程中遇到的异常情况的解释。我们的方法在NTHU-DDD上进行了实验，并通过最先进的异常检测方法进行基准测试，以使驱动器嗜睡。结果表明，所提出的模型在曲线（AUC）下达到了0.8740面积的检测率，并能够在某些情况下进行重大改进。
In this paper, an LSTM autoencoder-based architecture is utilized for drowsiness detection with ResNet-34 as feature extractor. The problem is considered as anomaly detection for a single subject; therefore, only the normal driving representations are learned and it is expected that drowsiness representations, yielding higher reconstruction losses, are to be distinguished according to the knowledge of the network. In our study, the confidence levels of normal and anomaly clips are investigated through the methodology of label assignment such that training performance of LSTM autoencoder and interpretation of anomalies encountered during testing are analyzed under varying confidence rates. Our method is experimented on NTHU-DDD and benchmarked with a state-of-the-art anomaly detection method for driver drowsiness. Results show that the proposed model achieves detection rate of 0.8740 area under curve (AUC) and is able to provide significant improvements on certain scenarios.
