Classification errors of the logistic regression classifiers built on the subsets of features derived by the RBFE procedure. The colored curves show errors of the classifiers utilizing the set of features, selected up to the current iteration (blue), the currently best subset (green), and the remaining features (red). Errors are averaged over the cross-validation folds; the range of the errors is shown in light colors. During feature selection their number was fixed at about 250 and varied during classification to achieve better accuracy.

(b) VAR features

(c) DEV features

(d) DERIV features
