In the post https://statcompute.wordpress.com/2017/09/03/variable-selection-with-elastic-net, it was shown how to optimize hyper-parameters, namely alpha and gamma, of the glmnet by using the built-in cv.glmnet() function. However, following a similar logic of hyper-parameter optimization shown in the post https://statcompute.wordpress.com/2019/02/10/direct-optimization-of-hyper-parameter, we can directly optimize ...
