RecBole-FairRec is a library toolkit built upon RecBole for reproducing and developing fairness-aware recommendation.

Highlights

• Easy-to-use: Our library shares unified API and input(atomic files) as RecBole.
• Conveniently learn and compare: Our library provides several fairess-metrics and frameworks for learning and comparing.
• Extensive FairRec library: Recently proposed fairness-aware algorithms can be easily equipped in our library.

Requirements

python>=3.7.0
recbole>=1.0.1
numpy>=1.20.3
torch>=1.11.0
tqdm>=4.62.3

Quick-Start

With the source code, you can use the provided script for initial usage of our library:

python run_recbole.py

If you want to change the models or datasets, just run the script by setting additional command parameters:

python run_recbole.py -m [model] -d [dataset] -c [config_files]

Implement Models

We list the models that we have implemented up to now:

• FOCF from Sirui Yao et al:Beyond Parity：Fairness Objectives for Collaborative Filtering(NIPS 2017). Note: We implement this model with ranking-based metrics, e.g. NDCG@K.
• PFCN from Yunqi Li et al:Towards Personalized Fairness based on Causal Notion(SIGIR 2021)
  • PFCN_MLP
  • PFCN_BiasedMF
  • PFCN_DMF
  • PFCN_PMF
• FairGo from Wu Le et al:Learning Fair Representations for Recommendation: A Graph-based Perspective (WWW 2021)
  • FairGo_PMF(WAP,LBA,LVA)
  • FairGo_GCN(WAP,LBA,LVA)
• NFCF from Rashidul Islam et al:Debiasing career recommendations with neural fair collaborative filtering (WWW 2021)

Datasets

The datasets used can be downloaded from Datasets Link.

Hyper-parameters

We train the models with the default parameter settings, suggested in their original paper.[link]

The Team

RecBole-FairRec is developed and maintained by members from RUCAIBox, the main developers is Jiakai Tang (@Tangjiakai).
