However, if you're looking for python version of it, take a look at these projects:

Update: I've tested some LibFM implementations on several datasets.
I included libFM and options proposed in this post.

- https://github.com/coreylynch/pyFM

Lovely minimalistic implementation of Factorization Machines using cython (previous version used numpy).

This library has an interface similar to scikit-learn. - http://ibayer.github.io/fastFM/index.html

fastFM is another option. Library supports both classification and regression.

Contains three different solvers (SGD, ALS, MCMC). ALS = alternative least squares.

In the paper written by author of algorithm, he argues that other algorithms are comparable to SGD.

This library is completely following scikit-learn interface (even deriving from BaseEstimator and appropriate mixin classes). - I was also looking for code in theano, but the only code I found was very dirty and minimalistic (so I'm not hoping it is usable)

Faced with some issues with existing libraries, I just built a python wrapper around libFM: https://github.com/jfloff/pywFM

Hi, Joao,

thanks for posting link.

I've looked through you repo.

I'm using the same approach now (skearn's dump_svm_light + calling libFM).

This takes 5 lines and does not require wrapper :)

Good thing about your wrapper is tha tit is able to get biases + interactions from LibFM.

Does this work with mcmc?

Yes, you can get that data. Good thing about the wrapper is that you also have the output converted so you can easily use it in iterations :)

Glad you liked the repo!

Cheers
