A DPP implementation on Deep Reinforcement Learning for Movies Recommendation System from the paper:
Zhao, X., Zhang, L., Xia, L., Ding, Z., Yin, D., & Tang, J. (2019). Deep reinforcement learning for list-wise recommendations.
The implementation is heavily built on the following code repo:
egipcy. (2020). List-wise recommendation framework based on deep reinforcement learning. https://github.com/egipcy/LIRD. GitHub.
This decision was made to run the experiment in the available time, and to built on top of a stable fundament.
- Python 3
- Tensorflow 1.15
- Numpy
- Scipy
- Dppy
Install required packages
run python deep-dpprl-dpp.py
The dataset is split into train, validation, and test sets to make the experiment as valid as possible.
By tuning the nb_episodes parameter the model is tested on diversifying performance through the episodes.
This project is heavily built on the LIRD model, and by using the following papers:
