RecBole-TRM

RecBole-TRM is a library built upon PyTorch and RecBole for reproducing and developing recommendation algorithms based on Transformers (TRMs). Our library includes algorithms covering two major categories:

• Sequential Recommendation: TiSASRec, SSE-PT, LightSANs, gMLP, CORE

Highlights

• Easy-to-use API: Our library shares unified API and input (atomic files) as RecBole.
• Fair reproducibility and comparison: Our library provides fair reproducibility and comparison in a systematic mechanism.
• Extensive Transformer library: Our library provides extensive API based on common Transformer layers, one can further develop new models easily based on our library.

Requirements

recbole>=1.0.0
pyg>=2.0.4
pytorch>=1.7.0
python>=3.7.0

Quick-Start

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

python run_recbole_trm.py

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

python run_recbole_trm.py -m [model] -d [dataset]

Implemented Models

We list currently supported models according to category:

Sequential Recommendation:

• TiSASRec from Li et al.: Time Interval Aware Self-Attention for Sequential Recommendation (WSDM 2020).
• SSE-PT from Wu et al.: SSE-PT: Sequential Recommendation Via Personalized Transformer (RecSys 2020).
• LightSANs from Fan et al.: Lighter and Better: Low-Rank Decomposed Self-Attention Networks for Next-Item Recommendation (SIGIR 2021).
• gMLP from Liu et al.: Pay Attention to MLPs (NeurIPS 2021).
• CORE from Hou et al.: CORE: Simple and Effective Session-based Recommendation within Consistent Representation Space (SIGIR 2022).

Experiments
