Integrating Structured Background Information into Time-Series Data Monitoring of Complex Systems
|Termin||Fr 18. Juni 2021|
|Kurzfassung||Monitoring of time series data is increasingly important due to massive data generated by complex systems, such as industrial production lines, meteorological sensor networks, or cloud computing centers. Typical time series monitoring tasks include: future value forecasting, detecting of outliers or computing the dependencies.
However, the already existing methods for time series monitoring tend to ignore the background information such as relationships between components or process structure that is available for almost any complex system. Such background information gives a context to the time series data, and can potentially improve the performance of time series monitoring tasks.
In this bachelor thesis, we show how to incorporate structured background information to improve three different time series monitoring tasks. We perform the experiments on the data from the cloud computing center, where we extract background information from system traces. Additionally, we investigate different representations and quality of background information and conclude that its usefulness is independent from a concrete time series monitoring task.
