Text Shot: Simulating human attitudes and behaviors could enable researchers to test interventions and theories and gain real-world insights.
We built an AI agent architecture that can simulate real people in ways far more complex than traditional approaches. Using this architecture, we created generative agents that simulate 1,000 individuals, each using an LLM paired with an in-depth interview transcript of the individual.
To test these generative agents, we evaluated the agents’ responses against the corresponding person’s responses to major social science surveys and experiments. We found that the agents replicated real participants’ responses 85% as accurately as the individuals replicated their own answers two weeks later on the General Social Survey.

Easy Ghost Imaging Simulations (and some codes to do it at home)

A few weeks ago I gave a short seminar on how to do very simple Ghost Imaging simulations. So simple that you can run then in your latptop in a few seconds (or minutes), and you can use them as building blocks to develop larger projects. I created a Github repo with all the codes needed, and I will explain how to use them a little bit here. This is just a quick text covering some of the slides of the seminar, which was aimed at people who are already familiar with Ghost Imaging, but not so […]

University of Georgia: Storm surge virtual reality simulation designed to save lives. “Weather the Storm, a virtual reality simulation that takes users through the effects of storm surge to communicate its devastating and sometimes fatal consequences, is now available for download. The simulation aims to empower coastal residents to actively prepare for hurricanes.”

Past decisions made with limited knowledge can come back to bite... hard.

I finally formalized "Model 1" last year. It's a detailed, fully-documented internal standard for modeling infra in #Django for water accounting, scheduling, simulation, and more. It’s not perfect, but it meets my needs and looks beautiful visualized, IMO.

Sir, ma'am, do you have a minute to talk about #evolution?

In these gloomy days, teaching #evolution is the safe harbour. Tomorrow the lecture is online, because I (and many students) are going to a strike in #Utrecht against budget cuts to higher education 🟥 , but I hope they will still enjoy these absolute classics:

Niklas, Karl J. "Evolutionary walks through a land plant morphospace." Journal of Experimental Botany 50.330 (1999): 39-52.

I still remember being awe-struck by the work of Karl Niklas on plant #biophysics and #morphogenesis when I was a 1st year student at the University of Warsaw. This was truly a portal to a world where everything in nature could be explained and had an underlying principle.

Budd, Graham E. "Morphospace." Current Biology 31.19 (2021): R1181-R1185.

While I am learning my part in French to explain #simulations of #evolution in Brussels for a Science is Wonderful show by @ERC_Research later this week.

Many mysteries surround the origin of the universe. 🎆 One of these concerns the ‘false vacuum decay’, exploring the dynamics of the ‘Big Bang’.💫 🌍 A team of scientists from JSC, the University of Leeds & the Institute of Science and Technology Austria used #quantum #simulations to examine it more closely. The results were published in Nature Physics. 👏 Dr Jaka Vodeb (JSC) explains these findings in an interview:

Hologram Electronics Chroma Console is this interesting multi-effects #pedal ppl seems to be using for lo-fi #tape #simulations. I'm using Generation Loss by Cooper FX to scratch that particular itch but probably will have to try it out sometimes in the future hologramelectronics.com/chroma

Today was a good day in #phdlife - I got some new perspectives as a result of very interesting conversations with colleagues. New #simulations are running!
Back to business! 🤓

[Observations and #simulations] In addition to #observations of protostars using #interferometers with ever-higher resolution, researchers are developing multidimensional numerical simulations.

The aim is to better understand the formation and evolution of the #protostellar disk and the #protostar through the different phases and scales of the collapse of a dense low- and high-mass core.

This Thursday, Benoît Commerçon, researcher @cnrs at the Centre de Recherche Astrophysique de Lyon (CRAL), will present to IRAPians the results obtained using “his” numerical experiments, as well as future developments ... irap.omp.eu/event/disk-and-pro
