arXiv:2411.13479v4 Announce Type: replace-cross Abstract: We consider conformal prediction for multivariate data and focus on hierarchical data, where some components are linear combinations of others. Intuitively, the hierarchical structure can be leveraged to reduce the size of prediction regions for the same coverage level. We implement this intuition by including a projection step (also called a reconciliation step) in the split conformal prediction [SCP] procedure, and prove that the resulting prediction regions are indeed globally smaller. We do so both under the classic objective of joi
The proliferation of complex, high-dimensional datasets necessitates more robust and efficient methods for uncertainty quantification in AI predictions.
This development improves the reliability and interpretability of AI models, particularly in applications where predictive confidence and hierarchical data structures are critical.
AI models can now generate prediction regions that are not only statistically sound but also leverage inherent data hierarchies to be more precise and smaller.
