🧬 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.

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!

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