Generalized Linear Models with the Exclusive Lasso Penalty

The ExclusiveLasso R package implements the Exclusive Lasso penalty as analyzed by Campbell and Allen (EJS, 2017), for Gaussian, logistic, and Poisson regression. The interface is glmnet compatible and the package supports both proximal gradient and coordinate descent solvers.

The package vignette is also notable for a thorough derivation of the back-tracking proximal Newton algorithm used for penalized GLMs, giving more detial than I have found elsewhere. Reading it would be useful for 1st or 2nd year Ph.D. students interested in efficient implementation of this family of algorithms.
