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.

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.

Advances in Complex Systems ACS is an international, peer-reviewed journal, uniquely publishing in multidisciplinary approaches, either empirical or theoretical, to the study of complex systems.

The first episode of our gentrification saga is finally open access!

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

Great turnout for our workshop on the effects of Recommender Systems on social environments

Latest work on human mobility! A great collaboration with colleagues at FBK. Look at the paper on @pnas.org 👇

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 👇

The KDD Lab Workshop 2024 just started in San Miniato, Italy.
Two days for sharing the last achievements and new horizons in research...

Big thanks to @ric-dicle.bsky.social for an outstanding lesson on unlocking the secrets of human mobility with digital data in our #GeospatialAnalytics course at the University of Pisa. Inspiring and eye-opening! 🌍📊🚶‍♂️ #HumanMobility

Thanks for tue amazing event in Pisa. I’m back home but looking forward to the next steps. Special thanks to @adtony.bsky.social @ric-dicle.bsky.social and @lucapappalardo.bsky.social!

Evolving Together: Human-AI Coevolution Is Said To Be Coming Whether Humanity Likes It Or Not A trending claim is that human-AI coevolution is underway and will expand. AI shapes humans, humans shape AI. Good or bad? Here's the inside scoop.
