Abstract: SVM is an effective classification method，the nature of learning is that it solves the original problem by the dual problem，but it does not directly obtain the feature importance.This article raises a new feature selection algorithm.Experiments show that the new feature selection algorithm and F-Score algorithm for calculating the same test data set is the result of the same descending order.The new feature selection algorithm is reasonable.
