[0063] In order to better illustrate the purpose and advantages of the present invention, the implementation of the method of the present invention will be further described in detail below in conjunction with examples.
[0064] Select 20newsgroups, Amazon reviews and RCV1 public data sets, of which 20newsgroups contains 20 news discussion groups with different topics, Amazon reviews are composed of more than 1.4 million reviews about products on the Amazon website, and select relevant reviews of 10 categories of products, RCV1 has Over 800,000 manually categorized press release stories, with text for 3 subtopics selected.
[0065] In order to verify that the parametric affine mapping established by the method of the present invention can improve the smoothness of the out-of-sample text embedding representation vector and improve the effect of text clustering and classification, the K-means algorithm is used for text clustering experiments and the 1-NN algorithm is used for Te...
