WebThe l east a bsolute s hrinkage and s election o perator, or lasso, as described in Tibshirani (1996) is a technique that has received a great deal of interest. As with ridge regression we assume the covariates are standardized. WebTechnically the Lasso model is optimizing the same objective function as the Elastic Net with l1_ratio=1.0 (no L2 penalty). Read more in the User Guide. Parameters: alphafloat, default=1.0. Constant that multiplies the L1 term, controlling regularization strength. alpha must be a non-negative float i.e. in [0, inf).
