WebSep 2, 2024 · Kernel ridge regression (KRR) is a popular machine learning technique for tasks related to both regression and classification. To improve the generalization ability of the KRR model, this paper suggests a twin KRR model for binary classification. WebMar 20, 2024 · Ridge regression is a regularized regression algorithm that performs L2 regularization that adds an L2 penalty, which equals the square of the magnitude of coefficients. All coefficients are shrunk by the same factor i.e none are eliminated. L2 regularization will not result in sparse models.

The association is a line in the case of a single input variable. Still, with the higher dimensions, the relationship can be assumed to be a hyperplane which connects the input features to the target variable.
