Embodiment Construction
[0062] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and implementation examples. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention.
[0063] The present invention provides a feedback clustering method based on cluster semantic feature analysis, such as figure 1 As shown, including the following steps:
[0064] Step 1, weighting K-means clustering based on feedback attributes to obtain optimal attribute weights, including the following steps:
[0065] Step 1.1, set the initial attribute weight:
[0066] Let X={x 1 ,x 2 ,...,X n } Is a data set with n elements, and any element x in the data set X i Represents a data point with m classification attributes, which can be expressed as x i = i1 ,x i2 ,...,X im> , The data ...
