Intrinsic feature selection
WebThe embedded methods wer tested, as the feature-selection algorithm is integrated as part of the learning algor [50], and we preferred to use ANN models in an independent step, … WebThe two-step feature selection methods can couple two effective feature selection methods to assemble an optimal feature set for building the prediction model . This method takes full advantages of the support vector machine recursive feature elimination (SVM-RFE), which can efficiently reduce noise and irrelevant features in the classification task.
