Polynomial regression is a form of linear regression in which the relationship between the independent variable (s) (predictors) and the dependent variable (response) is modeled as an n th degree polynomial. Masking occurs when the polynomial regression model is not able to distinguish between different classes because the polynomial degree is too low. Welcome to Windows 11! Whether you're new to Windows or upgrading from a previous version, this article will help you understand the basics of Windows 11. A polynomial is an algebraic expression that is made up of variables, constants, and exponents that are joined together using mathematical operations (addition, subtraction, multiplication, and division). If you want to fit a curved line to your data with scikit-learn using polynomial regression, you are in the right place.
