[Neural Networks] RGDAN: A random graph diffusion attention network for traffic prediction

This is a PyTorch implementation of Decomposition Dynamic Graph Conolutional Recurrent Network for Traffic Forecasting, as described in our paper: Jin Fan, Weng, Wenchao, Hao Tian, Huifeng Wu , Fu Zhu, Jia Wu RGDAN: A random graph diffusion attention network for traffic prediction,Neural Networks 2024.

Note

The original code for this paper was lost due to server damage a year ago, and there was a lack of awareness to save relevant data at that time. The current code has been reconstructed based on memory to provide a version for research reference. While it achieves good results, it may not match the performance reported in the paper due to unknown reasons. We appreciate your understanding.

Data Preparation

The relevant datasets have been placed in the "data" folder. To run the program, simply unzip the "PeMS.zip" and "METR.zip" files.

Requirements

Python 3.6.5, Pytorch 1.9.0, Numpy 1.16.3, argparse and configparser

Model Training

# METR
python train.py --dataset METR --adjdata data/adj_mx.pkl

# PeMS
python train.py --dataset PeMS --adjdata data/adj_mx_bay.pkl

#BJ
python train_BJ.py
