How do we stop model collapse in AI autophagy? In our ACM TIST paper, we show how perplexity-filtering mitigates model collapse by filtering out low-quality synthetic data. 📄 Paper here: dl.acm.org/doi/10.1145/... @danigambit.bsky.social

New paper out! How do we get mad at football? It turns out fan emotional response is a far from linear phenomenon. In fact, it is. a "bursty" one: long stretches of quiet punctuated by sudden, chaotic explosions of emotions. Check it out! @dsalvaz.bsky.social link.springer.com/article/10.1...

Temporal dynamics of emotions in Italian online soccer fandoms - EPJ Data Science

This #OpenAccess study from 'Machine Learning' represents the first attempt to study how the human-AI feedback loop reshapes human mobility patterns. bit.ly/4c64FvV @gmauro10.bsky.social @lucapappalardo.bsky.social #AI #ML

📢 New paper! We study urban location recommenders and their feedback with human mobility. Simulating this loop reveals a paradox: people explore more individually, yet city visits and encounters concentrate. Cities coevolve with AI, and inequality can grow. 📄 link.springer.com/article/10.1...

The best is yet to come!

Delighted to share that my group at CNR won a FIS Consolidator grant (the “Italian ERC”) to study City-AI Coevolution. We’ll investigate how the human-AI feedback loop shapes human mobility and urban life.

The first episode of our gentrification saga is finally open access! www.worldscientific.com/doi/10.1142/... @nicopedre.bsky.social @lucapappalardo.bsky.social

Everyone’s building AI—but how is it shaping us? A new EU law will open access for researchers to study AI’s real-world impact. But to make the most of it, we need the right methods. 📄 Our survey paper is your guide to doing just that.

How do recommender systems shape our behavior? 📄 We review 144 studies across domains, from social media to GenAI. 🧭 With the EU Digital Services Act, data access is now possible. Our survey offers a guide to studying recommender-driven risks. 🔗 arxiv.org/abs/2407.01630

Great turnout for our workshop on the effects of Recommender Systems on social environments @hhaiconference.bsky.social

Back in action with the Gentrification crew! @nicopedre.bsky.social @lucapappalardo.bsky.social Truly honoured to receive this award at @netsciconf.bsky.social in Maastricht. More updates coming soon!

I finally discussed my PhD thesis "Understanding and Modelling Urban Dynamics: A Human Mobility Approach". I'm not sure we understood everything, but we definitely modelled a lot. But in the end, we learnt and grew. Thanks to everyone who joined this journey in the science of journeys!

Excited that our paper "Human-AI Coevolution" is cited in the latest UN Human Development Report: "A Matter of Choice: People and Possibilities in the Age of AI"! 🌍🤖 📘 UN report here: hdr.undp.org/content/huma... 📘 Paper here: www.sciencedirect.com/science/arti...

We constantly ask our apps where to visit, eat or drink. AI tells us, and most of the time, we follow it. The loop continues. But do AIs favor certain places? How would we even know if we don’t own the platforms? We modeled this complex phenomenon, and results are fascinating! Spoiler: rich get…

A beautiful location for an amazing workshop. Thanks @nicopedre.bsky.social Tim, Karel and Renaud for making it happen!

How much do we get mad with italian soccer? Spoiler: a lot

Where and how do complexity science, AI, and society intersect? I think this perspective paper poses THE question we should address.
