ElasticNet
In many real cases, it's useful to apply both Ridge and Lasso regularization in order to force weight shrinkage and a global sparsity. It is possible by employing the ElasticNet regularization, defined as:
The strength of each regularization is controlled by the parameters λ1 and λ2. ElasticNet can yield excellent results whenever it's necessary to mitigate overfitting effects while encouraging sparsity. We are going to apply all the regularization techniques when discussing some deep learning architectures.
