STGFORMER_PRETRAIN_IMPUTE_NORM_PEMS-BAY

Spatial-Temporal Graph Transformer (Pretrain Impute Norm) - PEMS-BAY

Spatial-Temporal Graph Transformer (Pretrain Impute Norm) (STGFORMER_PRETRAIN_IMPUTE_NORM) trained on PEMS-BAY dataset for traffic speed forecasting.

Model Description

STGFormer with masked node pretraining + imputation on NORMALIZED data (per-timestep -> per-node curriculum)

Dataset

PEMS-BAY: Traffic speed data from highway sensors.

Usage

from utils.stgformer import load_from_hub

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

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

Training

Model was trained using the STGFORMER_PRETRAIN_IMPUTE_NORM implementation with default hyperparameters.
