-Fast algorithm to solve Lasso-like problems with dual extrapolation. Currently, the package handles the following problems: Lasso, Sparse Logistic regression, Group Lasso and Multitask Lasso.
-The estimators follow the scikit-learn API, come with automated cross-validation, and support sparse and dense data with feature centering and normalization.
-The solvers used allow for solving large scale problems with millions of features.

+The estimators follow the scikit-learn API, come with automated parallel cross-validation, and support both sparse and dense data, with optionnaly feature centering, normalization, and unpenalized intercept fitting.
+The solvers used allow for solving large scale problems with millions of features, up to 100 times faster than scikit-learn.
