Happy to share that our paper "AI-Generated Faces in the Real World: A Large-Scale Case Study of Twitter Profile Images" has been accepted at #RAID2024 🎉
Check out the preprint here: arxiv.org/pdf/2404.14244
Thanks to @Dede198904, @thorstenholz, Asja Fischer, and @ErwQui!

Exzellente Forschung, ausgezeichnete Nachwuchsförderung & hervorragende Vernetzung vor Ort: Die Forschung an der @ruhrunibochum trägt dazu bei, Informationstechnologien sicherer zu machen – davon profitieren wir, im Zeitalter von KI und Quantentechnologien, am Ende alle.
„Bochum hat sich in den vergangenen 20 Jahren zu einem Hotspot der IT-Sicherheitsforschung entwickelt", sagt MP @HendrikWuest. An der @ruhrunibochum arbeiten über 200 Wissenschaftlerinnen & Wissenschaftler z.B. daran, KI-generierte Bilder ohne Kennzeichnung als Fakes zu erkennen.
Code and data for our #CVPR2024 paper are now available at github.com/jonasricker/aerob….

Lots of people in CS are (almost surely) GPT-ing their peer reviews

Happy to announce AEROBLADE, a simple and training-free method for detecting images generated by Stable Diffusion, Midjourney, and more. To be presented at #CVPR2024.

I share this observation: Research using deep learning is now all about innovation. Understanding doesn't matter. This will work for a while, but I doubt we can have real scientifc progress without understanding. I think we need more of these dos & don'ts papers, unfortunately 🤷♂️

Menschen haben oft keine Chance, durch #KI erzeugte Bilder, Audios oder Videos von echten zu unterscheiden. Deswegen arbeiten Forschende des @CASA_EXC an einer automatisierten Erkennung. ^md news.rub.de/wissenschaft/202…

Mirror, mirror on the computer: Am I facing discrimination when applying for a job?
A lot of companies are using tools based on algorithms when deciding who gets the job – which can reproduce injustices. Help us develop fair algorithms: donate your #CV! ⤵️
