[ICDE'2023] STWave

📖 Introduction

This is a official PyTorch implementation of the paper: When Spatio-Temporal Meet Wavelets: Disentangled Traffic Forecasting via Efficient Spectral Graph Attention Networks.

⚡ Environment

PyTorch
fastdtw
PyWavelets

🔧 Data Preparation

PeMSD3 & PeMSD4 & PeMSD7 & PeMSD8

Download the data PeMSD* with code: p72z.
Unzip them to corresponding folders.

PeMSD7(M) & PeMSD7(L)

Download the data PeMSD7(M).
Email authors of STGCN to get the data PeMSD7(L).

Tips

The name of downloaded datasets should be consistent with the name in config files.
