Webb17 maj 2024 · Loss function = OLS + alpha * summation (squared coefficient values) In the above loss function, alpha is the parameter we need to select. A low alpha value can lead to over-fitting, whereas a high alpha value can lead to under-fitting. In scikit-learn, a ridge regression model is constructed by using the Ridge class.

Each element of X will be a date, and the corresponding element of y will be the associated kwh. Once you have that, you will want to use sklearn.linear_model.LinearRegression to do the regression. The documentation is here. Webb5 jan. 2024 · Linear regression is a simple and common type of predictive analysis. Linear regression attempts to model the relationship between two (or more) variables by fitting a straight line to the data. Put simply, linear regression attempts to predict the value of one variable, based on the value of another (or multiple other variables).
