"Superresolution" AI is weird - it can& #39;t recover info that doesn& #39;t exist in the low-res input so it invents detail.
This is PULSE, whose task is to find a high-res image that matches the low-res input. It& #39;s better at finding some solutions than others.

The AI tends to find matching faces in certain positions, so it can look weird if you give it something else.
I verified that yes, if you downscale the upscaled image on the right, you’ll get something that looks very much like the picture in the center. It& #39;s technically correct

The AI reconstructs what it’s been rewarded to see, and since it’s been trained to produce human faces, that’s what it will reconstruct. So if I were to feed it an image of a plush giraffe, for example
#PlushGiraffePerturbation
#PlushGiraffePerturbation
This AI can& #39;t ID a blurred face.
But a hypothetical AI that upscales low-res images to match faces in a police database would be both a horrifying misuse of this technology and not out of character with how law enforcement abuses facial recognition today https://www.washingtonpost.com/technology/2019/05/16/police-have-used-celebrity-lookalikes-distorted-images-boost-facial-recognition-results-research-finds/">https://www.washingtonpost.com/technolog...

Speaking of what the AI has been rewarded to reconstruct - shortly after the authors released PULSE, people began to notice...THIS https://twitter.com/Chicken3gg/status/1274314622447820801">https://twitter.com/Chicken3g...
Several people, including the authors of the original paper on PULSE, found that the AI had a noticeable tendency to produce white faces, even if the input image hadn’t been of a white person. https://twitter.com/osazuwa/status/1274444300894572546?s=20">https://twitter.com/osazuwa/s...
Biased AI is a well-documented phenomenon, but this particular image is striking because it& #39;s literally staring you in the face. https://www.theverge.com/21298762/face-depixelizer-ai-machine-learning-tool-pulse-stylegan-obama-bias">https://www.theverge.com/21298762/...
There could be many reasons that PULSE was biased.
Worth noting: The benchmark for upscaling faces is based on a dataset that is 90% white. An AI that& #39;s great at upscaling white faces but terrible otherwise could still qualify as state-of-the-art. This is definitely a problem.

A related problem: the huge lack of diversity in the field of artificial intelligence. Even an academic project with art as its main application matters & should not have gone all the way to publication before someone noticed that it was hugely biased. https://www.theguardian.com/technology/2019/apr/16/artificial-intelligence-lack-diversity-new-york-university-study">https://www.theguardian.com/technolog...
Several factors are contributing to the lack of diversity in AI, including anti-Black bias.

Ignorance is no excuse. AI& #39;s bias issues are catching up with it, and it& #39;s long past time.
These folks have studied AI bias for years. Follow them.
