SGMC: Spectral Graph Matrix Completion

Code for AAAI21 paper "Scalable and Explainable 1-Bit Matrix Completion via Graph Signal Learning".

Data Format

The implementation is desiged for top-N recommendations on implicit data, and thus it takes user-item pairs as input:

uid,sid
1,1

Installation

The program requires Python 3.7+ with NumPy, SciPy, Pandas and PySpark.

Note:

• To achieve the best performance, we highly recommend to use NumPy/SciPy with MKL Intel

Train and Test

After specifying the location of files train.csv/test_tr.csv/test_te.csv in runme.sh, it is quite simple to train and evaluate the model by

bash runme.sh
