Meta has built engagement-boosting algorithms that show pedophiles pictures of young girls, write @mhkeller & @jenvalentino. “The men engage,” says algorithm research scientist @sapiezynski. “The machine is doing exactly what you want it to do.” https://t.co/YYySrB3CXr

Advertisers of merchandise for young girls find that adult men can become their unintended audience. In a test ad, convicted sex offenders inquired about a child model.

The results hold for stock images or real people, StyleGAN generated images where we control for confounding factors, and realistic job ads (the same job will end up reaching different people depending on the demographics implied in the image).

FB algorithms classify race, gender, and age of people in ad images and make delivery decisions based on the predictions. Images of Black folks are shown more to B users; images of children are delivered more to women; images of young women reach older men.

It is now available in Norwegian here: https://t.co/SUZFZAZbdM but I'd love to see it translated into English: Poles are also the 2nd biggest minority in the UK and experience horrendous treatment there, esp since the run up to the Brexit referendum.

Polish people are the biggest immigrant minority in Norway, but their experience of othering is rarely discussed. My sister (so proud!) @EwaSapiezynska just published her 1st book “I am not your Pole” where she unpacks this through her own story and interviews w/ other Poles.

And since that also proved not enough, I finally had to downgrade matplotlib back to 3.4.3 and follow the original advice.
And if that wasn't enough, try this: import matplotlib matplotlib.rcParams['pdf.fonttype']=42 matplotlib.rcParams['ps.fonttype']=42 matplotlib.rcParams.update({ "pdf.use14corefonts": True })

Apropos absolutely no camera-ready deadline in particular here's how to remove Type 3 fonts from your matplotlib figures without compromising their looks (via https://t.co/2PsWHvt5on) import matplotlib matplotlib.rcParams['pdf.fonttype']=42 matplotlib.rcParams['ps.fonttype']=42
