WebJun 25, 2024 · Polynomial regression is a well-known machine learning model. It is a special case of linear regression, by the fact that we create some polynomial features before creating a linear regression. Or it can be considered as a linear regression with a feature space mapping (aka a polynomial kernel ). With this kernel trick, it is, sort of, possible ...
