Linear regression for machine learning
NettetLinear Regression is a supervised machine learning algorithm where the predicted output is continuous and has a constant slope. It’s used to predict values within a continuous range, (e.g. sales, price) rather than trying to classify them into categories (e.g. cat, dog). Follow along and check the 25 most common Linear Regression Interview … NettetLinear 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. The predicted outcome of an instance is a weighted sum of its p features.
