The invention discloses a
time sequence anomaly detection method based on multi-window clustering symbolization, and relates to the technical field of
anomaly detection, and the method comprises the following steps: building a cross-window feature drift capture baseline, segmenting an input
time sequence according to sliding
time windows, extracting the feature distribution of each time window, and building a continuous mapping model; and extracting the transition gradient of the clustering
centroid according to the
characteristic distribution change between the adjacent
time windows, and generating a dynamic drift monitoring matrix for describing the dynamic change of the
centroid. Through cross-window feature drift capture and
centroid synchronous remapping, space-time continuous updating of
symbol mapping is realized, faults and failures caused by centroid
mutation are eliminated, and the accuracy and stability of
anomaly detection are improved; and through abnormal mapping freezing control and symbol consistency
closed loop, a self-healing regulation and control mechanism is constructed, so that the
system has self-
recovery and self-stabilization capabilities, and continuity, reliability and robustness of a detection process are ensured.
