Model Classification

We classify the related works based on four parts: spatial topology construction, spatial dependency modeling, temporal dependency modeling and external features, as shown in the figure below, where the baselines in the benchmark are In bold type.

Requirements

• Python 3.6
• numpy == 1.19.4
• pandas == 1.1.1
• torch >= 1.1
• mxnet == 1.4.1
• tensorflow >= 2.4.0

Dependencies can be installed using the following command:

Usage

Commands for training model:

python train_benchmark.py --model 'model_name' --data 'data_name' >> log.txt 

More parameter information can be found in train_benchmark.py or the file in the directory of corrsponding model. You can refer to these parameters for experiments, and you can also adjust the parameters to obtain better results.
