🧬 New paper from my internship at @GoogleDeepMind We introduce Persona Generators: functions that generate diverse synthetic populations for arbitrary contexts. We use AlphaEvolve to optimize the generator code, hill-climbing on diversity metrics — not just likelihood — counteracting the mode-seeking behavior of LLM sampling for agent-based simulations. 🧵👇1/

🎙️Exciting news: Ep.15 of Keystone Concepts in Teaching is published! Prof. Kelly Knight & Dr. Christine Rosenfeld @GGSDepartment chat with us about how we might increase access to courses, even those in STEM like labs & field experiences: stearnscenter.gmu.edu/season-2-sprin…

The @matplotlib cheatsheets are 🔥🔥! 🌎 Fantastic overview of everything you need to know + 🧠 Quick glance can refresh your memory in seconds Five of them here: 👉 matplotlib.org/cheatsheets/ And if you find any concepts tricky, read matplotlib-journey.com! 🙂

Have you ever thought of trajectories as sentences? See the figure, it's not too weird a thought! Turns out we can use language modeling ideas to do trajectory modeling! Paper (arxiv.org/pdf/2409.15366) to be presented later today at ACM SIGSPATIAL. See 🧵for more details 👇

Travel survey data are vital for urban mobility assessments—but they’re often costly and difficult to collect. Could LLMs help us synthesize such data? Our latest work, in collaboration with @anas_ant and @dpfoser, and the Best Paper Winner🥇at #SIGSPATIAL24, shows they can! 🧵👇

Check out our award-winning work from #SIGSPATIAL24! Come for the synthetic travel survey data generation, stay for the thorough evaluation on this super tricky setting! Details in 🧵👇

Great presentation by @prb977 yesterday!

How can we leverage large language models (LLMs) to generate travel surveys for any city? Check out our new @SIGSPATIAL_GIS paper arxiv.org/abs/2409.00063 #UrbanMobility #AI

Our paper received the @SIGSPATIAL_GIS 2024 "BEST RESEARCH PAPER" Award!

Great talk just now by Jonathan at @SIGSPATIAL_GIS in Atlanta.
