摘要:

由于其无处不在和无处不在的性质,Wi-Fi网络有可能收集大规模,低成本和分类的多式联运数据。在本研究中,我们开发了一个半监督深度残差网络(ResNet)框架,利用从智能手机获得的Wi-Fi通信来进行交通模式检测。该框架是由位于多伦多市中心拥挤的市区的Wi-Fi传感器收集的数据进行评估。为了解决与标记数据汇集相关的固有困难和成本,我们通过实现框架的半监督部分来利用大量容易收集的低成本未标记数据。通过将ResNet架构作为框架的核心,我们利用了传统机器学习框架中没有考虑的高级功能。所提出的框架显示出良好的性能,与步行,骑自行车和驾驶模式的预测准确率分别为81.8%,82.5%和86.0%。

英文摘要:

Due to their ubiquitous and pervasive nature, Wi-Fi networks have the potential to collect large-scale, low-cost, and disaggregate data on multimodal transportation. In this study, we develop a semi-supervised deep residual network (ResNet) framework to utilize Wi-Fi communications obtained from smartphones for the purpose of transportation mode detection. This framework is evaluated on data collected by Wi-Fi sensors located in a congested urban area in downtown Toronto. To tackle the intrinsic difficulties and costs associated with labelled data collection, we utilize ample amount of easily collected low-cost unlabelled data by implementing the semi-supervised part of the framework. By incorporating a ResNet architecture as the core of the framework, we take advantage of the high-level features not considered in the traditional machine learning frameworks. The proposed framework shows a promising performance on the collected data, with a prediction accuracy of 81.8% for walking, 82.5% for biking and 86.0% for the driving mode.
