Extended Data Fig. 1: Unweighted evaluation of breast cancer prediction on the US test set.
From: International evaluation of an AI system for breast cancer screening
In contrast to in Fig. 2b, the sensitivity and specificity were computed without the use of inverse probability weights to account for the spectrum enrichment of the study population. Because hard negatives are overrepresented, the specificity of both the AI system and the human readers is reduced. The unweighted human sensitivity and specificity are 48.10% (n = 553) and 69.65% (n = 2,185), respectively.
