I hate all this bias bullshit because it makes the problem bigger than it actually is and passes the wrong idea to the general public.
A pedestrian detection system shouldn’t have as its goal to detect skin tones and different pedestrian sizes equally. There’s no benefit in that. It should do the best it can to reduce the false negative rates of pedestrian detection regardless, and hopefully do better than human drivers in the majority of scenarios. The error rates will be different due to the very nature of the task, and that’s ok.
This is what actually happens during research for the most part, but the media loves to stir some polarization and the public gives their clicks. Pushing for a “reduced bias model” is actually detrimental to the overall performance, because it incentivizes development of models that perform worse in scenarios they could have an edge just to serve an artificial demand for reduced bias.
I think you’re misunderstanding what the article is saying.
You’re correct that it isn’t the job of a system to detect someone’s skin color, and judge those people by it.
But the fact that AVs detect dark skinned people and short people at a lower effectiveness is a reflection of the lack of diversity in the tech staff designing and testing these systems as a whole.
They staff are designing the AVs to safely navigate in a world of people like them, but when the staff are overwhelmingly male, light skinned, young and single, and urban, and in the United States, a lot of considerations don’t even cross their minds.
Will the AVs recognize female pedestrians?
Do the sensors sense light spectrum wide enough to detect dark skinned people?
Will the AVs recognize someone with a walker or in a wheelchair, or some other mobility device?
Toddlers are small and unpredictable.
Bicyclists can fall over at any moment.
Are all these AVs being tested in cities being exposed to all the animals they might encounter in rural areas like sheep, llamas, otters, alligators and other animals who might be in the road?
How well will AVs tested in urban areas fare on twisty mountain roads that suddenly change from multi lane asphalt to narrow twisty dirt roads?
Will they recognize tractors and other farm or industrial vehicles on the road?
Will they recognize something you only encounter in a foreign country like an elephant or an orangutan or a rickshaw? Or what’s it going to do if it comes across that tomato festival in Spain?
Engineering isn’t magical: It’s the result of centuries of experimentation and recorded knowledge of what works and doesn’t work.
Releasing AVs on the entire world without testing them on every little thing they might encounter is just asking for trouble.
What’s required for safe driving without human intelligence is more mind boggling the more you think about it.
These are important questions, but addressing them for each model built independently and optimizing for a low “racial bias” is the wrong approach.
In academia we have reference datasets that serve as standard benchmarks for data driven prediction models like pedestrian detection. The numbers obtained on these datasets are usually the referentials used when comparing different models. By building comprehensive datasets we get models that work well across a multitude of scenarios.
Those are all good questions, but need to be addressed when building such datasets. And whether model M performs X% better to detect people of that skin color is not relevant, as long as the error rate of any skin color is not out of an acceptable rate.
The media has become ridiculously racist, they go out of their way to make every incident appear to be racial now
