New method ensures conformal prediction coverage with adaptive model depth

Researchers have developed a new method called Selection-Safe Conformal Early Exit for calibrating conformal prediction sets in models with adaptive depth. This approach ensures coverage guarantees without needing an alpha/L correction, even when a data-dependent exit is chosen. The method constructs a single terminal path score from prefix maxima, calibrates a quantile, and returns nested prefix sets that are guaranteed to contain the valid terminal set. Experiments on CIFAR-100 with a ViT-L/16 model demonstrated improved coverage and set size compared to naive layerwise selection, particularly when the number of candidate exits is large relative to the calibration set size.
