PPT-Maxent Models and Discriminative Estimation

Generative vs Discriminative models Christopher Manning Introduction So far weve looked at generative models Language models Naive Bayes But there is now much use of conditional or discriminative probabilistic models in NLP Speech IR and ML generally. g Gaussian so only the parameters eg mean and variance need to be estimated Maximum Likelihood Bayesian Estimation Non parametric density estimation Assume NO knowledge about the density Kernel Density Estimation Nearest Neighbor Rule brPage 3br CSC Carl .
