A note on the group lasso and a sparse group lasso
J. Friedman, T. Hastie, R. Tibshirani
We consider the group lasso penalty for the linear model. We note that the standard algorithm for solving the problem assumes that the model matrices in each group are orthonormal.…

Sparse inverse covariance estimation with the lasso
Jerome Friedman, Trevor Hastie, Robert Tibshirani
We consider the problem of estimating sparse graphs by a lasso penalty applied to the inverse covariance matrix. Using a coordinate descent procedure for the lasso, we develop a si…
