You built a model using Lasso regularization but some important features were wrongly set to zero. How would you modify your approach to keep these features?
- Combine with ElasticNet
- Decrease L1 penalty
- Increase L1 penalty
- Switch to Ridge
Combining with ElasticNet allows for balancing between L1 and L2 penalties, thus avoiding complete elimination of important features by the L1 penalty.
