New Geometry for Conformal Prediction Regions Explored

This paper delves into the geometric properties of full conformal prediction (FullCP) regions, particularly those generated by an empirical energy-form pairwise score. It explores how convexity of a candidate score alone does not guarantee connected FullCP regions. The research introduces specific conditions under which comparison regions are guaranteed to contain a common minimizer, leading to star-shaped exact conformal regions. The findings are detailed for power distances $\rho_\beta(x,y)=\|x-y\|\^\beta$ where $\beta \ge 1$, with a focus on the univariate $\beta=1$ case where FullCP regions are shown to be closed intervals. For $1 < \beta < 2$ and $m \ge 2$, the paper provides explicit, data-checkable bounds that enable certified inner and outer radial envelopes with specific Hausdorff guarantees. AI

IMPACT This research could lead to more robust and interpretable uncertainty quantification in machine learning models.
