Method Detail

getThresholds

double[] getThresholds()

thresholds

DoubleArrayParam thresholds()

Param for Thresholds in multi-class classification to adjust the probability of predicting each class. Array must have length equal to the number of classes, with values > 0 excepting that at most one value may be 0. The class with largest value p/t is predicted, where p is the original probability of that class and t is the class's threshold.
