- W2381981226 abstract "Aiming at the defects of term frequency inverse document frequency( TFIDF) algorithm,this paper introduced the theory of class discrimination to the traditional TFIDF algorithm. Through the comparison of the classification effects between improved TFIDF algorithm and some other commonly used feature selection algorithms,it proved that the improved algorithm had a higher precision and recall rate than the other algorithms,therefore the effect of the feature selection was better." @default.
