Adaptive Denoising Training for Recommendation.

This is the pytorch implementation of our paper at WSDM 2021:

Denoising Implicit Feedback for Recommendation.
Wenjie Wang, Fuli Feng, Xiangnan He, Liqiang Nie, Tat-Seng Chua.

• Anaconda 3
• python 3.7.3
• pytorch 1.4.0
• numpy 1.16.4

For others, please refer to the file env.yaml.

python main.py --dataset=$1 --model=$2 --drop_rate=$3 --num_gradual=$4 --gpu=$5

or use run.sh

sh run.sh dataset model drop_rate num_gradual gpu_id

The output will be in the ./log/xxx folder.

sh run.sh dataset model alpha gpu_id

We provide the code to inference based on the well-trained model parameters.

python inference.py --dataset=$1 --model=$2 --drop_rate=$3 --num_gradual=$4 --gpu=$5

1. Train GMF by T_CE on Yelp:

python main.py --dataset=yelp --model=GMF --drop_rate=0.1 --num_gradual=30000 --gpu=0

2. Train NeuMF by R_CE on Amazon_book

python main.py --dataset=amazon_book --model=NeuMF-end --alpha=_0.25 --gpu=0

We release all training logs in ./log folder. The hyperparameter settings can be found in the log file. The well-trained parameter files are too big to upload to Github. I will upload to drives later and share it here.
