I'll be giving a talk about my research Tues, Apr 22 at Princeton Center for Statistics & Machine Learning: "With enough data and the right algorithms is your future predictable? Some evidence from LLMs and complete population-scale data" More info: csml.princeton.edu/events/enoug...

Happy to share the results and open-source code for our benchmark test of GPUs in secure computing environment. Thank you to our wonderful colleagues at ‪@esciencecenter.bsky.social‬. Code is open-sourced for others to use and improve. No private data required.
In the latest blog, we learn how the open-source benchmark compares training speed across different supercomputers, including secure environments. Key takeaways? Hardware differences drive performance gaps and multi-GPU scaling is efficient. Learn more:

I'm teaching my first course! A seminar on "Machine Behavior."

Readings are a mix of NLP, CSS-y, and ML work on how machines (focus LLMs) "behave" within sociotechnical systems and on how they can be used to study human behavior.

Feels fitting to have our very first-ever post be to celebrate two #CITP Associated Faculty members, Professor Aleksandra Korolova & Professor Olga Russakovsky, who were both awarded the Presidential Early Career Award for Scientists & Engineers from the White House this week! 🎉 💯 📖

No plans for a 2nd edition of Bit by Bit. I'm - slowly - working on a new book on a different topic. It took me years to write Bit by Bit, & I think this new book will take even longer . . . but let's hope not.

Ethics doesn't have to be too abstract. You can lead with real examples from real CSS research that have sparked debate and then show students how to reason about them.

Here are some other teaching materials from people using Bit by Bit in their classes: www.bitbybitbook.com/en/teaching/
Bit By Bit: Social Research in the Digital Age
www.bitbybitbook.com

At Summer Institutes in Computational Social Science (SICSS) we did ethics first & it worked well. It was a good way to get people talking and exposed to different disciplinary norms, both of which are good for learning. Here's what we did at SICSS: sicss.io/2021/princet...
