示例1: incorporateOneInstance
import cc.mallet.types.Labeling; //导入方法依赖的package包/类
private void incorporateOneInstance (Instance instance, double instanceWeight)
{
Labeling labeling = instance.getLabeling ();
if (labeling == null) return; // Handle unlabeled instances by skipping them
FeatureVector fv = (FeatureVector) instance.getData ();
double oneNorm = fv.oneNorm();
if (oneNorm <= 0) return; // Skip instances that have no features present
if (docLengthNormalization > 0)
// Make the document have counts that sum to docLengthNormalization
// I.e., if 20, it would be as if the document had 20 words.
instanceWeight *= docLengthNormalization / oneNorm;
assert (instanceWeight > 0 && !Double.isInfinite(instanceWeight));
for (int lpos = 0; lpos < labeling.numLocations(); lpos++) {
int li = labeling.indexAtLocation (lpos);
double labelWeight = labeling.valueAtLocation (lpos);
if (labelWeight == 0) continue;
//System.out.println ("NaiveBayesTrainer me.increment "+ labelWeight * instanceWeight);
me[li].increment (fv, labelWeight * instanceWeight);
// This relies on labelWeight summing to 1 over all labels
pe.increment (li, labelWeight * instanceWeight);
}
