Code for NeurIPS'20 paper Trading Personalization for Accuracy: Data Debugging in Collaborative Filtering

Requirements

python3
numpy
scipy

Usage

python main.py --mode=test

Run the above command to get the result on the movielens dataset.

To run the debug process, configure other parameters in the command, where the mode parameter is set to debug.

Here is the code fragment about the settings of hyperparameters.
