Citing fastFM=============The library fastFM is an academic project. The time and resources spent developing fastFM are therefore justifiedby the number of citations of the software. If you publish scientific articles using fastFM, please cite the following article (bibtex entry `citation.bib <http://jmlr.org/papers/v17/15-355.bib>`_).Bayer, I. "fastFM: A Library for Factorization Machines" Journal of Machine Learning Research 17, pp. 1-5 (2016)fastFM: A Library for Factorization Machines============================================.. image:: https://travis-ci.org/ibayer/fastFM.svg?branch=master:target: https://travis-ci.org/ibayer/fastFM.. image:: https://img.shields.io/badge/platform-OSX|Linux-lightgrey.svg:target: https://travis-ci.org/ibayer/fastFM.. image:: https://img.shields.io/pypi/l/Django.svg:target: https://travis-ci.org/ibayer/fastFMThis repository allows you to use Factorization Machines in **Python** (2.7 & 3.x) with the well known **scikit-learn API**.All performance critical code as been written in C and wrapped with Cython. fastFM providesstochastic gradient descent (SGD) and coordinate descent (CD) optimization routines as well as Markov Chain Monte Carlo (MCMC) for Bayesian inference.The solvers can be used for regression, classification and ranking problems. Detailed usage instructions can be found in the `online documentation  <http://ibayer.github.io/fastFM>`_ and on `arXiv <http://arxiv.org/abs/1505.00641>`_.Supported Operating Systems---------------------------fastFM has a continuous integration / testing servers (Travis) for **Linux (Ubuntu 14.04 LTS)**and **OS X Mavericks**. Other OS are not actively supported.Usage-----.. code-block:: pythonfrom fastFM import alsfm = als.FMRegression(n_iter=1000, init_stdev=0.1, rank=2, l2_reg_w=0.1, l2_reg_V=0.5)fm.fit(X_train, y_train)y_pred = fm.predict(X_test)Tutorials and other information are available `here <http://arxiv.org/abs/1505.00641>`_.The C code is available as `subrepository <https://github.com/ibayer/fastFM-core>`_ and providesa stand alone command line interface.

This is thefastest way to get feedback and allows `Travis CI <https://travis-ci.org/ibayer/fastFM>`_ to run checks on your changes.Most information you need to setup your **development environment** can be learned by adapting the great instructions on https://github.com/scikit-learn/scikit-learn/blob/master/CONTRIBUTING.md . Please ensure that your contribution conforms to the `PEP8 <http://www.python.org/dev/peps/pep-0008/>`_ Coding Style and includes unit tests where appropriate.
