[IJCAI-24] Spatial-Temporal-Decoupled Masked Pre-training for Spatiotemporal Forecasting

Framework

Google Scholar

Due to the change in title, you can find our article by searching STD-MAE directly.

Preprint Link (All six datasets [PEMS03, 04, 07, 08, PEMS-BAY, and METR-LA] are included. You can also check the performace of PEMSD7M, PEMSD7L, and EXPY-TKY datasets in this repo.)

Performance on Spatiotemporal Forecasting Benchmarks

  • Please note you can get a much better performance on PEMS07 dataset using pre-training length of 2016. But it is a time-cosuming operation.

💿 Dependencies

OS

Linux systems (e.g. Ubuntu and CentOS).

Python

The code is built based on Python 3.9, PyTorch 1.13.0, and EasyTorch. You can install PyTorch following the instruction in PyTorch.

Miniconda or Anaconda are recommended to create a virtual python environment.

We implement our code based on BasicTS.

Other Dependencies

pip install -r requirements.txt

Getting started

STD-MAE has now been integrated into BasicTS. You can also check many baselines there.

Download Data

You can download data from BasicTS and unzip it.

Preparing Data

  • Pre-process Data

You can pre-process all datasets by

cd /path/to/your/project
bash scripts/data_preparation/all.sh

Then the dataset directory will look like this:

datasets
   ├─PEMS03
   ├─PEMS04
   ├─PEMS07
   ├─PEMS08
   ├─raw_data
   |    ├─PEMS03
   |    ├─PEMS04
   |    ├─PEMS07
   |    ├─PEMS08
   ├─README.md

Pre-training on S-MAE and T-MAE

cd /path/yourproject

Then run the folloing command to run in Linux screen.

screen -d -m python stdmae/run.py --cfg='stdmae/TMAE_PEMS03.py' --gpus='0' 

screen -d -m python stdmae/run.py --cfg='stdmae/TMAE_PEMS04.py' --gpus='0'

screen -d -m python stdmae/run.py --cfg='stdmae/TMAE_PEMS07.py' --gpus='0' 

screen -d -m python stdmae/run.py --cfg='stdmae/TMAE_PEMS08.py' --gpus='0'

screen -d -m python stdmae/run.py --cfg='stdmae/SMAE_PEMS03.py' --gpus='0' 

screen -d -m python stdmae/run.py --cfg='stdmae/SMAE_PEMS04.py' --gpus='0'

screen -d -m python stdmae/run.py --cfg='stdmae/SMAE_PEMS07.py' --gpus='0' 

screen -d -m python stdmae/run.py --cfg='stdmae/SMAE_PEMS08.py' --gpus='0'

Downstream Predictor

After pre-training , copy your pre-trained best checkpoint to mask_save/. For example:

cp checkpoints/TMAE_200/064b0e96c042028c0ec44856f9511e4c/TMAE_best_val_MAE.pt mask_save/TMAE_PEMS04_864.pt
cp checkpoints/SMAE_200/50cd1e77146b15f9071b638c04568779/SMAE_best_val_MAE.pt mask_save/SMAE_PEMS04_864.pt

Then run the predictor as :

screen -d -m python stdmae/run.py --cfg='stdmae/STDMAE_PEMS04.py' --gpus='0' 

screen -d -m python stdmae/run.py --cfg='stdmae/STDMAE_PEMS03.py' --gpus='0' 

screen -d -m python stdmae/run.py --cfg='stdmae/STDMAE_PEMS08.py' --gpus='0'

screen -d -m python stdmae/run.py --cfg='stdmae/STDMAE_PEMS07.py' --gpus='0'
  • To find the best result in logs, you can search best_ in the log files.
