Webb概率分布律[law of probability distribution]简称概率律或概率分布。 WebbThe mid point inside the simplex represents predicting the three classes with equal probability (i.e., 1/3, 1/3, 1/3). Each arrow starts at the uncalibrated probabilities and end with the arrow head at the calibrated probability. The color of the arrow represents the true class of that test sample.
