# PM2.5 Forecasting Demo Data
This dataset stores the lightweight artifacts used by the Hugging Face Space demo:
https://huggingface.co/spaces/sumit1703/pm25-forecasting
The files are precomputed outputs from the ANRF AISEHack Phase 2 Theme 2 Pollution Forecasting project. The Space uses these artifacts only for visualization. It does not run live model inference, training, or torch at runtime.
## Files
| File | Description |
|---|---|
| `demo_preds.npy` | Precomputed PM2.5 forecast predictions for demo windows. Shape: `(22, 140, 124, 16)` |
| `demo_inputs.npy` | Input PM2.5 history windows used for comparison. Shape: `(22, 10, 140, 124)` |
| `lat_lon.npy` | Latitude/longitude grid used for map axes. |
| `demo_stats.json` | Feature normalization/statistics metadata from the preprocessing pipeline. |
| `sample_indices.npy` | Original sample/window indices used by the demo. Shape: `(22,)` |
## Intended Use
This dataset is intended for the companion Gradio demo only. It allows the app to load saved prediction artifacts from the Hugging Face Hub instead of storing `.npy` files inside the GitHub repository.
## Source Project
- GitHub: https://github.com/sumitjadhav1703/pm25-forecasting-demo
- Live Space: https://huggingface.co/spaces/sumit1703/pm25-forecasting
- Kaggle Competition: https://www.kaggle.com/competitions/anrf-aise-hack-phase-2-theme-2-pollution-forecasting-iitd
## Notes and Limitations
- These files are for demo visualization, not full model training.
- The dataset contains a small subset of demo windows, not the complete competition dataset.
- The predictions are precomputed and static.
- The Space downloads these files at startup using `huggingface_hub`.
