STDEN

This is the implementation of Spatio-temporal Differential Equation Network (STDEN) in paper Towards Physics-guided Neural Networks for Traffic Flow Prediction.

Requirement

• scipy>=1.5.2
• numpy>=1.19.1
• pandas>=1.1.5
• pyyaml>=5.3.1
• pytorch>=1.7.1
• future>=0.18.2
• torchdiffeq>=0.2.0

Dependency can be installed using the following command:

pip install -r requirements.txt

Model Traning and Evaluation

One can run the code by

# traning for dataset GT-221
python stden_train.py --config_filename=configs/stden_gt.yaml

# testing for dataset GT-221
python stden_eval.py --config_filename=configs/stden_gt.yaml

The configuration file of all datasets are as follows:

dataset	config file
GT-221	stden_gt.yaml
WRS-393	stden_wrs.yaml
ZGC-564	stden_zgc.yaml

PS: The data is not public and I am not allowed to distribute it.
