Three lightning talks by KDD Lab of Pisa at @css-conference.bsky.social in Siena, in a few minutes in the plenary room!

🚦 How diverse are your city’s routes?

Today at @ic2s2.bsky.social (lightning talks), @gcornacchia.bsky.social presents: “Route Diversification in Road Networks”.

We introduce DiverCity, a metric to quantify how traffic can spread across alternative routes.

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.

Honored to host Prof. Marta González at our KDD Lab in Pisa! Her talk on the Science of Cities at Scuola Normale Superiore (@sns.it) was deeply inspiring.

A true privilege to meet the researcher who sparked my passion for human mobility. #UrbanScience #Mobility #Cities

Latest work on human mobility! A great collaboration with colleagues at FBK. Look at the paper on @pnas.org 👇
New in PNAS! 📢 lnkd.in/d7z2VEjh
👉 We show how combining individual & collective behavior boosts out-of-routine mobility prediction

👉 We found collective behavior strongly impacts individual mobility in dense urban areas.

👉 The model is robust to severe behavioral changes (e.g., COVID pandemic)

I just came across a paper full of hallucinated citations.
www.nature.com/articles/s41...

I have four urgent questions:
1) Which version of ChatGPT wrote this?
2) Which version of ChatGPT peer-reviewed it?
3) How many of these slip through “reputable” journals every day?
4) Are we being trolled?

The human-AI feedback loop strikes back! This time in the urban environment. Look at our latest work 👇
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!
