373 results about "Generative model" patented technology

In statistical classification, including machine learning, 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): Given an observable variable X and a target variable Y, a generative model is a statistical model of the joint probability distribution on X × Y, P(X,Y); A discriminative model is a model of the conditional probability of the target Y, given an observation x, symbolically, P(Y|X=x); and Classifiers computed without using a probability model are also referred to loosely as "discriminative".
