Fast algorithm to solve the Lasso with dual extrapolation

Please visit https://mathurinm.github.io/celer/ for the latest version of the documentation.

Assuming you have a working Python environment, e.g. with Anaconda you can install celer with pip.

From a console or terminal install celer with pip:

pip install -U celer

From a console or terminal clone the repository and install Celer:

git clone https://github.com/mathurinm/celer.git
cd celer/
pip install -e .

To build the documentation you will need to run:

pip install -U sphinx_gallery sphinx_bootstrap_theme
cd doc/
make html

You find on the documentation examples on the Leukemia dataset (comparison with scikit-learn) and on the Finance/log1p dataset (more significant, but it takes times to download the data, preprocess it, and compute the path).

All dependencies are in ./setup.py file.
