    • setWeights

      public void setWeights(double[] weights, int[] weightLabels)

      nr_weight, weight_label, and weight are used to change the penalty for some classes (If the weight for a class is not changed, it is set to 1). This is useful for training classifier using unbalanced input data or with asymmetric misclassification cost.

      Each weight[i] corresponds to weight_label[i], meaning that the penalty of class weight_label[i] is scaled by a factor of weight[i].

      If you do not want to change penalty for any of the classes, just set nr_weight to 0.
