Proposes new measures and frameworks for calibrated predictions in machine learning, suggesting improved methodologies.

The aim is to enhance the understanding and measurement of calibrated predictions in machine learning systems.
Reviewed the concept of calibrated predictions and proposed a shift to ℓ1 expected calibration error.
Developed a measure-theoretic generalization of calibrated predictions across various output types and structures.
Introduced a framework in category theory to reframe calibration as a coherence condition in Bayesian inversion.
Showed that using ℓ1 expected calibration error provides tighter bounds than ℓ∞ max calibration error.
Established a unification theorem characterizing calibrated predictions in terms of specified loss families.
Outlined a new operadic structure for loss families that maintain alignment with Bayesian targets.

Alfredo Sepulveda-Jimenez (2026) studied this question.
