# Spatial-Temporal Graph Transformer (Pretrained) - PEMS-BAY

Spatial-Temporal Graph Transformer (Pretrained) (STGFORMER_PRETRAINED) trained on PEMS-BAY dataset for traffic speed forecasting.

## Model Description

STGFormer pretrained checkpoint for PEMS-BAY. This checkpoint contains pretrained model weights and imputation head from masked node pretraining. Use with load_from config option.



## Dataset

**PEMS-BAY**: Traffic speed data from highway sensors.

## Usage

```python
from utils.stgformer import load_from_hub

# Load model from Hub
model, scaler = load_from_hub("PEMS-BAY", hf_repo_prefix="STGFORMER_PRETRAINED")

# Get predictions
from utils.stgformer import get_predictions
predictions = get_predictions(model, scaler, test_dataset)
```

## Training

Model was trained using the STGFORMER_PRETRAINED implementation with default hyperparameters.
