Figure 5From: Ovarian cancer detection from metabolomic liquid chromatography/mass spectrometry data by support vector machinesDistribution of Feature Occurrence Frequency over the LOOCV Evaluation. Distribution of the frequency of the features that occur in the feature selection results over the LOOCV evaluation for (A) SVMRFE, (B) SVMRFE_NL, (C) L1SVM, and (D) SVMRW methods. The bar indicates the number of features at a given feature occurrence frequency (red when frequency = 0.8 otherwise blue).Back to article page
