Joint Policy-Value Learning for Recommendation

Source code for our paper "Joint Policy-Value Learning for Recommendation" published at KDD 2020.

Reproducibility

To generate a virtual Python environment that holds all the packages our work relies on, run:

virtualenv -p python3 dual_bandit
source dual_bandit/bin/activate
pip3 install -r requirements.txt

Now, you can run any of the three ''RunABTest'' files to run all experimental results corresponding to a column in Fig. 2 of the paper. For example:

python3 src/RunABTest_Uniform.py
