Research on Multilevel Classification of High-Speed Railway Signal Equipment Fault Based on Text Mining
In this paper, the multilevel classification model of high-speed railway signal equipment fault based on text mining technology is proposed for the data of high-speed railway signal fault. An improved feature representation method of TF-IDF is proposed to extract the feature of fault text data of si...
