w.r.t by 豌豆先生 In folder src includes three file that can run independently, first ,run >>python keyWords.py to get classLabel.txt and trainLeft.txt ... then run >>python crossTest.py ,result is TDIDF+NB: F = 95.5 TDIDF+SVM(LinearSVC): F = 97.5 TDIDF+RF: F = 97.5 Counter+LinearSVC: F = 98.2 Hash+TDIDF+LinearSVC: F = 97.8 ... then run >> python IG.py,use IG(information gain),or MI(multiple information),or WLLR result is: MI: F = 97.5 IG,WLLR: F = 98.5 LDA is testing,look forward to the result
