Some of the important applications of time series anomaly detection are healthcare, eco-system disturbances, intrusion detection and aircraft system health management. Although there has been extensive work on anomaly detection (1), most of the techniques look for individual objects that are different from normal objects but do not consider the sequence aspect of the data into consideration. In this thesis, we analyze the state of the art of time series anomaly detection techniques and present a survey.

Through extensive experimental evaluation of the proposed techniques on the data sets collected across diverse domains, we conclude that our techniques perform well across many datasets.","abstract_html":"This thesis deals with the problem of anomaly detection for time series data.
