The models include linear regression, two-class logistic regression, and multi- nomial regression problems while the penalties include ℓ<sub>1</sub> (the lasso), ℓ<sub>2</sub> (ridge regression) and mixtures of the two (the elastic net). The algorithms use cyclical coordinate descent, computed along a regularization path. The methods can handle large problems and can also deal efficiently with sparse features. In comparative timings we find that the new algorithms are considerably faster than competing methods. ER -
