WebMar 10, 2024 · Generative Model as an Expressive Vehicle. In our approach, we consider the labeling functions as implicitly describing a generative model. To give a quick refresher: given data points x, having unknown labels y that we want to predict, in a discriminative approach we model P(y x) directly, while in a generative approach we model P(x,y) = … WebJan 2, 2024 · Examples of Discriminative Models. Support Vector Machines. Support vector machines operate by drawing a decision boundary between data points, finding the decision boundary that best separates the different classes in the dataset. The SVM algorithm draws either lines or hyperplanes that separate points, for 2-dimensional …
