Usage

1. Install the dependencies

   pip install -r requirements.txt
   

2. Obtain the dataset from Google Drive and extract it to the root directory of the project. Make sure the extracted folder is named dataset and has the following structure:

   dataset
   ├── electricity
   │   └── electricity.csv
   ├── ETT-small
   │   ├── ETTh1.csv
   │   ├── ETTh2.csv
   │   ├── ETTm1.csv
   │   └── ETTm2.csv
   ├── PEMS
   │   ├── PEMS03.npz
   │   ├── PEMS04.npz
   │   ├── PEMS07.npz
   │   └── PEMS08.csv
   ├── Solar
   │   └── solar_AL.txt
   ├── traffic
   │   └── traffic.csv
   └── weather
       └── weather.csv
   

3. Train and evaluate the model. All the training scripts are located in the scripts directory. For example, to train the model on the Solar-Energy dataset, run the following command:

   sh ./scripts/TimeBridge.sh
