Fixed version (ground truth):

    if (sample.vector.length != vector.length) {
      continue;
    }
    double distance;
    if (gestureType == GestureLibrary.SEQUENCE_SENSITIVE) {
      distance=GestureUtilities.cosineDistance(sample.vector,vector);
    }
 else {
      distance=GestureUtilities.squaredEuclideanDistance(sample.vector,vector);
    }
    double weight;
    if (distance == 0) {
      weight=Double.MAX_VALUE;
    }
 else {
      weight=1 / distance;
    }
    Double score=label2score.get(sample.label);
    if (score == null || weight > score) {
