Linear regression model coefficients

Model coefficients, also known as regression coefficients or weights, are the values assigned to the features (independent variables) in a regression model. In a linear regression model, the relationship between the input features (X) and the predicted output (y) is represented as: Here: The model coefficients are estimated during the training of the regression model.…

What is PolynomialFeatures preprocessing technique?

PolynomialFeatures is a preprocessing technique used in machine learning, particularly in polynomial regression. It transforms an input feature matrix by adding new features that are polynomial combinations of the original features. For example, if you have a feature (x), PolynomialFeatures can generate additional features like , etc., up to a specified degree. This allows the…
