Zonolayer is a Python package for last-layer uncertainty modeling via zonotopic representations.
It provides zonotopic output bounds for neural networks with interval-bounded outputs, enabling precise and interpretable uncertainty quantification in regression tasks.
- Compute zonotopic bounds for last-layer outputs.
- Compatible with PyTorch networks.
- Modular, research-friendly, and easy to use.
By default, Zonolayer relies on NumPy for all numerical computations and interval handling.
If you require more advanced interval arithmetic (e.g., using pyinterval or other specialized packages), you can install the optional dependencies and modify the code accordingly, or submit a request for support to be added. I appreciate any and all feedback.
