Abstract

The embodiment of the invention provides a method and device for identifying a data pattern of a time sequence. The method includes the steps of obtaining the time sequence of the data pattern to be identified, wherein each moment in the time sequence is correspondingly provided with an observation value for observing the data pattern; according to the observation values and events corresponding to a preset value range, determining the corresponding event of each segment in the time sequence; according to the determined corresponding event of each segment, determining events of the same class,and generating weighted structures of the events of the same class; according to the weighted structures, selecting a target weighted structure from a weighted structure set of known data patterns; adopting a known data pattern corresponding to the target weighted structure as an identification result of the data pattern. The device executes the method above. The method and device can break the limitation of the data pattern of the time sequence and improve the accuracy of the identification result.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of data processing, and in particular to a method and device for identifying time series data patterns. Background technique [0002] With the development of information technology, data is growing at an exponential rate. Many data are stored in the form of time series when they are stored, that is, the observations of the observation pattern are recorded at each moment. The data pattern can represent the rising / falling trend in the process of stock trading, the changing trend of the heartbeat frequency of the electrocardiogram, the changing trend of air temperature and so on. The data pattern in the time series not only contains data attributes, but also has a strong dependency relationship with each time, and such dependencies often contain a lot of information. The analysis of these relationships is of great value and can often produce great economic benefits. [0003] In the rela...
