Cordier & Lacombe - Boosting AI Reliability: Uncertainty Quantification with MAPIE
Learn how MAPIE boosts AI reliability through uncertainty quantification, enabling safer predictions in critical applications like healthcare and autonomous systems.
-
MAPIE is a framework for uncertainty quantification in AI that works with any ML model and requires minimal assumptions
-
Key features include:
- Distribution-free coverage guarantees
- Model-agnostic design - works with any ML algorithm
- Supports classification, regression and time series
- Built-in conformal prediction capabilities
- Handles imbalanced datasets through Mondrian strategy
-
Provides meaningful uncertainty intervals/prediction sets with guaranteed coverage levels (e.g. 95% confidence)
-
Helps detect:
- Out of distribution samples
- Model degradation
- Data drift
- When model predictions cannot be trusted
-
Main use cases:
- Risk control in sensitive applications
- Regulatory compliance
- Safety-critical systems (autonomous vehicles, medical)
- Time series forecasting with changing patterns
-
Implementation requires:
- Training data
- Calibration data
- Test data
- Desired confidence level
-
Limitations:
- Requires calibration dataset
- More conservative predictions with smaller calibration sets
- May return infinite intervals in some cases
- Coverage guarantees are in expectation
