1. Environment Requirements

• Ubuntu 16.04
• Anaconda with Python 3.6.9
• CUDA 10.0

Note: The specific python package list of our environment is included in the requirements.txt. The tensorflow version can be 1.12~1.15. The installation may need several minutes if there is no environmental conflicts.

2. Hardware requirements Needs a Linux server with larger than 32GB memory. GPU cores are optional but recommended.

3. Running

• Download datasets from their original sources
• Convert then into matlab matrix formats (rows: users, columns: items, value: ratings)
• Execute "python run.py"

Note: The logs will show the training loss and the test results. The estimated running time is from tens of minutes to hours, depending on the dataset size.
