How to import lasso regression
Web25 dec. 2024 · The penalty term in Elastic Nets is a combination of both absolute value and squared value penalties. Elastic Net first emerged as a result of critique on Lasso, whose variable selection can be too dependent on data and thus unstable. The solution is to combine the penalties of Ridge regression and Lasso to get the best of both worlds. WebRandomized Lasso works by resampling the train data and computing a Lasso on each resampling. In short, the features selected more often are good features. It is also known …
