Happy to share that my paper (with Fabrizio Germano & @vicengomez.bsky.social) "Ranking for Engagement: How Social Media Algorithms Fuel Misinformation & Polarization" has found a great home @jpube.bsky.social ! 🎉 A thread on what we do and why it matters 🧵👇 www.sciencedirect.com/science/arti...

#Recerca Creix la polarització ideològica i la difusió de notícies esbiaixades o falses a Facebook, segons un estudi d'Emma Fraxanet, investigadora @enginyeria-upf.bsky.social conjuntament amb ndreas Kaltenbrunner (UOC) i Fabrizio Germano (UPF, BSE). ℹ️ tuit.cat/bEvGy #FakeNews #SoMe

I just created a new word. And I am proud of it 💪: LLM-castinating, refers to the act of using large language models (LLMs) as a way to delay actual work. It’s like regular procrastination, but with AI as your enabler. And it is also less 'pro' 🤓

📰 @nnekaokolo4.bsky.social became the first student to get a PhD thanks to the Dorcas Muthoni #Scholarship, set up by @enginyeria-upf.bsky.social 🗣️"I aim to advance the development of reliable algorithms for sequential decision-making tasks such as autonomous driving" ℹ️ tuit.cat/8fue1
