Embodiment Construction
[0047] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.
[0048] In one embodiment, such as figure 1 As shown, a one-dimensional time series anomaly detection method is provided, including the following steps:
[0049] Step 102, extract sample points from the one-dimensional time series; for each sample point, extract sample context information of the sample point through a sliding window; use an encoder to reduce the dimensionality of the sample context information to obtain sample low-dimensional embedded data.
[0050] Among them, the one-dimensional time series is extracted from the business system, and the business system c...
