Perfect example of how not proactively making an algorithm anti-racist can yield results that end up being racist. If you train a machine learning algorithm on photos with predominantly white faces, your algorithm is going to think people with lighter skin are more important thank people with darker skin.
Why are people downvoting this? The parent is correct. If you don't test your models adequately then they'll have holes like this one.
HN doesn't like talking about race or numerous other "controversial" topics. This story is already flagged off the front page.
> HN doesn't like talking about race or numerous other "controversial" topics.

There was plenty of discussions on HN when GitHub was renaming master/slave terminology [0] and when other open source projects were doing the same. Essentially they break the HN guidelines when they 'like' if it is a company / person they 'like'.

On the other hand, when a topic attacks their 'narrative' or attacks their side of the argument from someone they don't like, they downvote, flag and censor and make sure it is never seen. Even if it is factual and has evidence.

I find this on hacker news by time site. These discussions become inflated by politics, so are moderated.
> that end up being racist

Conditional on the relatively novel definition of racism, this is correct.

I would love to see this novel definition of racism used more consistently and thoroughgoingly — to encompass all the manifold races, not just the 19th-century "continental races" taxonomy.

This assessment sounds correct. The silver lining here is that engineers will pay more attention to algorithm biases in the future.
So was all this BLM virtue signalling by Twitter Inc. all for nothing? Since they have a biased algorithm failing to detect non-white faces and preferring to select lighter faces in the same picture? Oh dear.

Companies pointing fingers at 'the system' should really use a mirror and ask themselves if they are really the baddies, since there's always three fingers point back at you. Looks like it was really an empty gesture after all.

This comment is pretty good if you read it satirically.
Believe me. I wish it was satire. But the irony is that it seems the so-called 'diversity' and 'anti-racists' virtue signallers are now becoming the actual racists. Especially on Twitter.

What a shame.

Knowing the owners of Twitter I hope they completely shut down the service while they fix this.
Wow.

(nothing else to say)

In case anyone else did not realize this and is as confused as I was, apparently you can attach more than one photo to a tweet, and Twitter will then show previews of all of them in a gallery. The previews are formed by taking some part of the original image. Clicking on any of the previews opens a view of the corresponding full image.

I knew about twitter taking a part of an image and using that for a preview, but had not realized that there could be more than one image in a tweet.

Consistent in the title is misleading because this is essentially n=1. The Twitter user did try to transform the image in order to produce a different result but we don’t know if there is something not race based in Mitch’s face that the algorithm prefer’s over Obama’s. We also don’t know if the user has cherry picked this example.
