From: Biases in human perception of facial age are present and more exaggerated in current AI technology
(a) Age estimation accuracy for the different AIs compared to average human performance. As was the case for human observers, AI performance showed a large decrease in accuracy for faces of older adults compared to faces of younger adults. This effect was larger for AI compared to human performance. (b) The ageing effect of smiling for the different age groups—smiling faces were estimated as older than neutral faces of the same people. Overall, this effect was larger for AI (younger adults), and showed a sharper decrease with age. The inset shows the mean accuracy data (across age group, gender and facial expression) for each AI and each of the human observers. Group averages are indicated by the horizontal lines. Although there was variability in age estimation accuracy in both groups, humans were less variable and more accurate.
