reseq's Introduction

ReSeq

This is the official PyTorch implementation for the paper:

Reciprocal Sequential Recommendation. RecSys 2023

Overview

We proposes a reciprocal sequential recommendation method, named ReSeq, in which we formulate reciprocal recommendation as a distinctive sequence matching task and perform matching prediction based on bilateral dynamic behavior sequences.

Requirements

torch==1.10.1+cu113
cudatoolkit==11.3

Dataset

dataset_path in config.yaml should contain the following files:

dataset_path/
├── {train/valid_user/valid_item/test_user/test_item}.pkl
├── {user_his/item_his}.pkl
└── {user_token/item_token}.pkl

Run

cd ./run
python auto_run.py

Acknowledgement

The implementation is based on the open-source recommendation library RecBole and RecBole-PJF.
