In statistical classification, two main approaches are called the generative approach and the discriminative approach. These compute classifiers by different approaches, differing in the degree of statistical modelling. Terminology is inconsistent, but three major types can be distinguished, following Jebara (2004): 1. A generative model is a statistical model of the joint probability distribution on given observable … WebbWe are directly putting a probability over the class given all of the data we’ve observed P(c d1, d2, d3).
