中文简介: | 近年来,分析和检测城市中无处不在的传感器的事件一直是一个重要目标。能够通过监测城市传感器数据自动检测事件的不同技术已在几个智慧城市得到有效应用,以改善市民的日常生活。然而,对如此庞大的数据流的分析往往会干扰智能城市场景中出现的几个约束。例如,不可能雇佣人类神谕来持续监控每个数据流,为这些模型提供知识并注释过去的实例。因此,需要开发新技术来构建高效的监督学习模型,以应对城市数据泛滥。我们的方法做出了以下贡献:(i)我们通过整合来自城市数据的流式输入,有效地构建了监督学习模型的问题,以及(ii)我们提出了一种新的框架,能够应对流式城市数据事件检测中出现的限制,需要从精心选择的实例中提取标签。 |
课程简介: | Analyzing and detecting events from ubiquitous sensors across the city has been an important goal in recent years. Different techniques that are able to automatically detect events by monitoring urban sensor’s data have been efficiently applied in several smart cities to improve the citizens everyday life. However, the analysis of such voluminous data streams often interferes with several constraints that arise in smart cities scenarios. For example it is impossible to hire human oracles that will monitor each data stream continuously to provide knowledge to these models and to annotate past instances. Thus, the development of novel techniques is required in order to build efficient supervised learning models that will be able to cope with urban data deluge. Our approach makes the following contributions: (i) we formulate the problem of building supervised learning models efficiently by incorporating streaming input from urban data, and (ii) we present a novel framework that is able to cope with the restrictions that arise in the event detection of streaming urban data, requiring labels from carefully selected instances. |
