How does the objective function differ between Ridge, Lasso, and ElasticNet?
- No difference
- Ridge and Lasso have the same objective
- Ridge uses L1, Lasso uses L2, ElasticNet uses neither
- Ridge uses L2, Lasso uses L1, ElasticNet uses both
Ridge's objective function includes an L2 penalty, Lasso's includes an L1 penalty, and ElasticNet's includes both L1 and L2 penalties.
