The eye opening thing here is not that the AI failed, but why it failed. At start the AI is like a baby, it doesn't know anything or have any opinions. By teaching it using a set of data, in this case a set of resumes and the outcome then it can form an opinion. The AI becoming biased tells that the "teacher" was biased also. So actually Amazon's recruiting process seems to be a mess with the technical skills on the…
> The number of women and men in the data set shouldn't matter (algorithms learn that even if there was 1 woman, if she was hired then it will be positive about future woman candidates). This is incorrect. The key thing to keep in mind is that they are not just predicting who is a good candidate, they are also ranking by the certainty of their prediction. Lower numbers of female candidates could plausibly lead to low…
I don't think that's true. "No bias" means that gender is irrelevant (i.e. its correlation with outcome is 0%). Therefore the system shouldn't even take it into account - it would evaluate both men and women just by other criteria (experience, technical skills, etc), and it would have equal amounts of data for both (because it wouldn't even see them as different).
You need bias to even separate the dataset into distinct categories.
