As an extension of this photographs of individuals with darker skin required more lighting than photographs of individuals with darker skin.
I don't know all of what goes into the ML for facial recognition and I am sure there are people far smarter than me working on it (and making way more money than me to boot), but I guess my thought here is that some variation of Poe's Law applies. I know that people are quick to jump to condemn something as racist but sometimes there really are just honest mistakes.
I have a hard time believing that anyone at any level of the AWS structure set out to produce a racist facial recognition, but rather it may have just been an honest over site and rather than rushing to crucify them we should instead look at it as a learning opportunity to help develop further the field of facial recognition.
EDIT: I wanted to clarify that although I don't think it was done purposefully I don't think it doesn't bespeak a problem; my intention was rather to serve as a suggestion that we should sometimes temper the often strong reaction produced when labeling something racist, and focus our efforts on identifying and solving the issue rather than trying to act punitive. To forestall objections I do recognize this is an issue that does require correction, and that it does bespeak a larger societal problem that has real consequences for real people ever day, but in my experience we will get more progress by attempting to work together in a spirit of cooperation rather than a spirit of anger and vengance.
