Embodiment Construction
[0028] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.
[0029] Before introducing the fuzzy matching-based time series anomaly pattern recognition method and device, the definition of pattern anomaly is given as follows:
[0030] In the embodiment of the present invention, an in-depth study can be performed by defining an abnormal pattern and searching in sequences to obtain real abnormal samples. Among them, the definition of mode anomaly is given: For multiple continuous brightness segments such as S1,...,Sn, etc., which have a high similarity with the mode of interest in the embodi...
