Example 6 with FeatureNode

use of Classifier.supervised.liblinear.FeatureNode in project IR_Base by Linda-sunshine.

the class Utils method createLibLinearFV.

public static Feature[] createLibLinearFV(HashMap<Integer, Double> spVct) {
    Feature[] node = new Feature[spVct.size()];
    int fid = 0;
    for (_SparseFeature fv : createSpVct(spVct)) // svm's feature index starts from 1
    node[fid++] = new FeatureNode(1 + fv.getIndex(), fv.getValue());
    return node;
}
