Linear Multivariate Linear Regression Using Scikit Learn. In this tutorial we are going to use the Linear Models from Sklearn library. We are also going to use the same test data used in Multivariate Linear Regression From Scratch With Python tutorial. Introduction. Scikit-learn is one of the most popular open source machine learning library for python.

Linear Multivariate Linear Regression in Scikit-Learn. In this section, you’ll learn how to conduct linear regression using multiple variables. In this case, rather than plotting a line, you’re plotting a plane in multiple dimensions. However, the phenomenon is still referred to as linear since the data grows at a linear rate.

Linear SciKit Learn Linear Regression Multiple Features - Multivariate Linear Regression. Previously, we looked at a simple dataset containing only one feature column (X as a 1D vector) and one target column. We can extend this model to include multiple feature columns (X as a 2D matrix) such that:

Regression
1. Ordinary Least Squares¶ LinearRegression fits a linear model with coefficients \(w = (w_1, , w_p)\) to minimize the residual sum of squares between the observed targets in the dataset, and the targets predicted by the linear approximation.
2. Ridge regression and classification¶ 1.1.2.1. Regression¶ Ridge regression addresses some of the problems of Ordinary Least Squares by imposing a penalty on the size of the coefficients.
3. Lasso¶ The Lasso is a linear model that estimates sparse coefficients. It is useful in some contexts due to its tendency to prefer solutions with fewer non-zero coefficients, effectively reducing the number of features upon which the given solution is dependent.
4. Multi-task Lasso¶ The MultiTaskLasso is a linear model that estimates sparse coefficients for multiple regression problems jointly: y is a 2D array, of shape (n_samples, n_tasks).
5. Elastic-Net¶ ElasticNet is a linear regression model trained with both \(\ell_1\) and \(\ell_2\)-norm regularization of the coefficients. This combination allows for learning a sparse model where few of the weights are non-zero like Lasso, while still maintaining the regularization properties of Ridge.
6. Multi-task Elastic-Net¶ The MultiTaskElasticNet is an elastic-net model that estimates sparse coefficients for multiple regression problems jointly: Y is a 2D array of shape (n_samples, n_tasks).
7. Least Angle Regression¶ Least-angle regression (LARS) is a regression algorithm for high-dimensional data, developed by Bradley Efron, Trevor Hastie, Iain Johnstone and Robert Tibshirani.
8. LARS Lasso¶ LassoLars is a lasso model implemented using the LARS algorithm, and unlike the implementation based on coordinate descent, this yields the exact solution, which is piecewise linear as a function of the norm of its coefficients.
9. Orthogonal Matching Pursuit (OMP)¶ OrthogonalMatchingPursuit and orthogonal_mp implements the OMP algorithm for approximating the fit of a linear model with constraints imposed on the number of non-zero coefficients (ie.
10. Bayesian Regression¶ Bayesian regression techniques can be used to include regularization parameters in the estimation procedure: the regularization parameter is not set in a hard sense but tuned to the data at hand.

Regression Linear regression is one of the fundamental algorithms in machine learning, and it’s based on simple mathematics. Linear regression works on the principle of formula of a straight line, mathematically denoted as y = mx + c, where m is the slope of the line and c is the intercept. x is the the set of features and y is the target variable.
