Overview

daisyRec is a Python toolkit developed for benchmarking top-N recommendation task. The name DAISY stands for multi-Dimension fAir comparIson for recommender SYstem.

The figure below shows the overall framework of DaisyRec-v2.0.

This repository is used for publishing. If you are interested in details of our experiments ranking results, try to reach this repo file.

We really appreciate these repositories to help us improve the code efficiency:

How to Run

Make sure you have a CUDA enviroment to accelarate since the deep-learning models could be based on it.

1. Install from pip

pip install daisyRec

2. Clone from github

git clone https://github.com/AmazingDD/daisyRec.git && cd daisyRec

• Example codes are listed in run_examples, try to refer them and find out how to use daisy; you can also implement these codes by moving them into daisyRec/.

• The GUI Command Generator for test.py and tune.py, which can assist you to quikly write arguments and run the fair comparison experiments, is now available here.

  The generated command will be like this:

  python tune.py --param1=20 --param2=30 ....
  python test.py --param1=20 --param2=30 ....
  

  We highly recommend you to implement the code with our GUI firstly!

Documentation

The documentation of DaisyRec is available here, which provides detailed explanations for all arguments.

Implemented Algorithms

Models in daisyRec only take triples <user, item, rating> into account, so FM-related models will be specialized accrodingly. Below are the algorithms implemented in daisyRec. More baselines will be added later.
