A polynomial is a function that takes the form f (x) = c0 + c1 x + c2 x2 ⋯ cn xn where n is the degree of the polynomial and c is a set of coefficients. RMSE of polynomial regression is 10.120437473614711. R2 of polynomial regression is 0.8537647164420812. We can see that RMSE has decreased and R²-score has increased as compared to the linear line. If we try to fit a cubic curve (degree=3) to the dataset, we can see that it passes through more data points than the quadratic and the linear plots.

Thus, the polynomial regression y = b*x^2+a might yield a better model (e.g. for predictions) then the linear regression model y = b Polynomial regression is a regression algorithm which models the relationship between dependent and the independent variable is modeled such that the dependent variable Y is an nth degree function of the independent variable Y. The Polynomial regression is also called as multiple linear regression models in ML. the techniques for fitting linear regression model can be used for fitting the polynomial regression model. For example: 2 yxx 01 2 or 2 E()yxx 01 2 is a polynomial regression model in one variable and is called a second-order model or quadratic model. What is Polynomial Regression?

This type of regression takes the form: Y = β0 + β1X + β2X2 + … + βhXh + ε where h is the “degree” of the polynomial. Advantages of using Polynomial Regression: Polynomial provides the best approximation of the relationship between the dependent and independent variable. A Broad range of function can be fit under it. Polynomial basically fits a wide range of curvature.
