pyfms
A Theano-based Python implementation of factorization machines, based on the model presented in Factorization Machines (Rendle 2010).
Features
Sample weighting
For binary classification, this implementation uses a logit function combined with a cross entropy loss function.
Extensibility of algorithms for: regularization, loss function optimization, and the error function
Support for sparse data
Requirements
pyfms supports Python 2.7 and Python 3.x.
Linux and Mac are supported.
Windows is supported with Theano properly installed. The recommended way to install Theano on Windows is using Anaconda.
> conda install theano
Other operating systems may be compatible if Theano can be properly installed.
