It includes metadata for age, gender, and ethnicity, making it a cornerstone for studying demographic bias in AI. Why "Verified" Status Matters
: It contains approximately 55,134 unique images of about 13,000 subjects. Time Span : Data was collected between 2003 and late 2007 . morph ii dataset verified
Even with verified labels, the dataset is heavily skewed toward African American males. Verified age labels do not correct for demographic sampling bias. A model trained on verified MORPH II may perform well on African American males but poorly on Caucasian females or Asian subjects. Researchers must apply reweighting or debiasing techniques separately. It includes metadata for age, gender, and ethnicity,
While widely cited, researchers have identified inconsistencies in the original raw MORPH II data, leading to "verified" or "cleaned" subsets. Even with verified labels, the dataset is heavily
While the original dataset is popular, researchers have identified "interesting" inconsistencies—such as self-reported age and gender errors. This has led to the creation of verified subsets University of North Carolina Wilmington | UNCW MORPH-II Inconsistencies and Cleaning : A notable whitepaper from details the process of correcting these errors.
