A method merges statistical risk control with Early-Exit Neural Networks, enabling efficient inference by providing explicit, user-specified statistical guarantees on the quality of early predictions and uncertainty estimates. It consistently keeps prediction errors within predefined bounds while achieving considerable computational speed-ups across various machine learning tasks.
Key insights
- Statistical risk control provides explicit guarantees that early-exit predictions will meet predefined performance criteria, enhancing the trustworthiness of dynamic computation.
- Allowing risk estimation to account for "overthinking" (where early exits outperform final layers) leads to less conservative exit decisions and greater computational efficiency.
- The framework successfully extends risk control beyond simple prediction accuracy to encompass the quality of predictive distributions, offering more comprehensive safety assurances.
