Linear regression machine learning.
Linear models can be used to model the dependence of a regression target y on some features x. The learned relationships are linear and can be written for a single instance i as follows: y = β0 +β1x1 +…+βpxp+ϵ y = β 0 + β 1 x 1 + … + β p x p + ϵ. The predicted outcome of an instance is a weighted sum of its p features.
