Dependencies

• Python 2.7
• numpy
• scipy
• cython

Usage

The benchmark is implemented in Python. For efficiency purpose, the core algorithms are written as Python extension using C++.

1. Download the package: https://github.com/wsdream/PPCF/archive/master.zip,

   or use Git: git clone https://github.com/wsdream/PPCF.git.

2. Download WS-DREAM datasets to the data folder.

3. Build extension modules based on Cython

   $ cd PPCF/
   $ python setup.py build_ext --inplace
   

4. Run the demo scripts

   $ cd PPCF/demo/P-PMF
   $ python run_rt.py
   $ python run_tp.py 
   

5. Check the evaluation results in "result/" directory. Note that we have already provided the results of 20 random runs in the result directory for your quick reference.
