Description

technical field [0001] The present invention relates to the technical field of information processing, in particular to a time series anomaly detection method, device and equipment. Background technique [0002] Time series data is the most common observation index in the field of operation and maintenance. Its anomaly detection refers to the use of algorithms to judge the abnormal points in the data at equal intervals, so as to lay the foundation for subsequent fault location and other processing. [0003] Traditional time series anomaly detection methods can be divided into three categories: statistical methods, machine learning methods, and time series decomposition methods. Statistical methods are applicable to limited data types. It is difficult to adjust the parameters of machine learning algorithms. Time series decomposition algorithms usually face the problem of sudden change point and periodic prediction in the decomposition process, and it is easy to attribute tr...
