COINS: Any-Stage-Valid and Utility-Oriented Sequential Conformal Prediction

In clinical diagnosis, sequential screening, and cascaded prediction systems, information is often acquired in stages, with intermediate predictions guiding whether to act on the available evidence or defer action to gather further information. We study sequential predictive inference in these settings, aiming to const...

COINS: Any-Stage-Valid and Utility-Oriented Sequential Conformal Prediction

Many predictive workflows update uncertainty as information is acquired and use intermediate reports to determine whether to stop or deploy further resources. We study conformal inference in this setting, treating the resulting prediction sequence as the inferential object. We require any-stage validity, which protects...
