I see at least two main sources of bias: 1) your training data does not have enough people with dark skin or African American face features, 2) your hardware and image processing pipeline relies on color contrast or skin brightness. One way to measure bias is to compare the average error rare across ethnic groups.
- centimeter 6y ago> your training data does not have enough people with dark skin or African American face features This isn’t the issue - the issue is lower variance across black faces in any basis. > your hardware and image processing pipeline relies on color contrast That is how vision works.
- brnt 6y agoYou keep repeating black faces have lower variance, but you never back this up. Personally I find it a preposterous thesis, I find the opposite to be true. I know for a fact genetic diversity is highest among Africans. By being so convinced of this without showing any proof you are running to risk of proving the point at the root of this issue: we are not addressing our bias in building the system. Not only in our data, but in your case perhaps even not in our thinking.
- centimeter 6y ago> I know for a fact genetic diversity is highest among Africans. This doesn't mean what you think it means. In particular, it does not imply wider phenotypic variance.
- brnt 6y agoNo, but it makes it more likely. Meanwhile, you had a nights sleep and still show us nothing.
- cycomanic 6y agoYou continue to bring this up without evidence. Sounds to me you're just stating your own prejudice see https://en.m.wikipedia.org/wiki/Cross-race_effect https://en.m.wikipedia.org/wiki/Cross-race_effect
- centimeter 6y agoI calculated it myself in a CV course in university. The same effect was observed by others. I didn't read it somewhere. This shouldn't surprise anyone - white people have tremendously higher variance in color alone (skin, hair, and eyes).
