Embodiment Construction
[0059] Embodiments of the present application are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals denote 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 application, and should not be construed as limiting the present application.
[0060] The method and device for detecting anomalies in multi-time series data according to the embodiments of the present application will be described below with reference to the accompanying drawings.
[0061] Specifically, Table 1 lists the existing unsupervised algorithms and their shortcomings. The LSTM-NDT algorithm uses a deterministic method to model multiple time series. DAGMM uses a stochastic method but ignores the time dependence of time series data. LSTM- VAE is simply a combination of long short-term memory ne...
