Linear regression machine learning

This discussion focuses on the very first supervised machine learning method, regression analysis, which results in a linear prediction model. The phrase regression analysis for predicting unknown values of a variable was created in the 19th century by a first cousin of Charles Darwin, Sir Francis Galton, one of the founders of social science.

Polynomial regression: extending linear models with basis functions¶ One common pattern within machine learning is to use linear models trained on nonlinear functions of the data. This approach maintains the generally fast performance of linear methods, while allowing them to fit a much wider range of data. Linear Regression: In statistics, linear regression is a linear approach for modeling the relationship between a scalar dependent variable y and one or more explanatory variables (or independent variables) denoted X. The case of one explanatory variable is called simple linear regression.
