Polynomial regression is a type of regression analysis that models the relationship between a dependent variable and one or more independent variables as an nth-degree polynomial. It is used when the relationship between the independent and dependent variables is nonlinear.
Examples in Machine Learning
Table 1 shows an example of polynomial regression for a dataset containing two independent variables, x1 and x2, and a dependent variable, y.

| 3.0 | 0.1 | 3.1 |
| 4.0 | 0.2 | 4.5 |
| 5.0 | 0.4 | 5.3 |
We can fit a polynomial curve of degree 2 to this dataset, resulting in the following equation:
y = 0.2 + 0.5*x1 + 0.3*x2 + 0.1*x1^2 – 0.2*x1*x2 – 0.1*x2^2
This equation can be used to predict the value of y for new values of x1 and x2.
