机器学习笔记之Naive Bayes

机器学习笔记之Naive BayesA family of classifiers that are quite similar to linear models, but they train faster. Price for its efficiency is that these models often provide worse generalization performances.The reason that naïve Bayes models are so efficient i

Linear Models for RegressionFor regression, general prediction formula should look like: y = w[0]*x[0]+w[1]*x[1]+…+w[p]*x[p]+bFor a data with a singLe feature, this formula would be y =b+w[0]*x[0]Linear Regression, also knowns as ordinary leat squ
