PySofia is a python wrapper around the methods present in the C++ sofia-ml library. These include Stochastic Gradient Descent implementations of some ranking algorithms, notably RankSVM.
- cython >= 0.17 (previous versions will not work)
- numpy
- A C++ compiler (gcc will do)
You will not need to install sofia-ml since it is incuded in this distribution
$ pip install -U pysofia
pysofia.train_sgd
Trains a model using stochastic gradient descent. See docstring for more details.
pysofia.compat.RankSVM implements an estimator following the conventions used in scikit-learn.
