Anomaly Detection of Time Series Data Based on HTM-Attention
Existing industrial time series data anomaly detection algorithms do not fully consider the temporal data on time dependence.An improved HTM(Hierarchical Temporal Memory)-Attention algorithm is proposed to address this problem.The algorithm combines the HTM algorithm with the attention mechanism to learn the temporal dependencies between data.It is validated on both univariate and multivariate time series data.By introducing the attention mechanism,the algorithm can focus on the important parts of the input data,further improving the efficiency and accuracy of anomaly detection.Experimental results show that the proposed algorithm can effectively detect various types of time series anomalies and has higher accuracy and lower running time than other commonly used unsupervised anomaly detection algorithms.This algorithm has great potential in the application of industrial time series data anomaly detection.
