Webb4 feb. 2024 · Discriminative vs Generative models Machine Learning models are often categorized into discriminative and generative models. This distinction arises from the probabilistic formulation we use, to build and train those models. Discriminative models learn the probability of a label y y based on a data point x x. http://www.cjig.cn/html/jig/2024/3/20240309.htm
