Exciting news for those who want to experiment with Mixture of Experts (MoE) models but find training and fine-tuning too expensive! With MyShell.AI, we are thrilled to introduce JetMoE, a Llama-2-level model trained for under 0.1 million $. With 8B total and 2.2B active

I'm super excited to see this out! It has been a privilege to work closely with Dashun Wang Ben Jones Alicia Loffler, my CSSI labmates Jian Gao Binglu Wang Zihang Lin Yifang WANG Erzhuo Shao, and the rest of the team on this project over the past years!

It’s that time of the year again! #ICSSI starts tomorrow!!! Action packed three days. The festival for #scienceofscience. Look forward to seeing everyone at the National Academies tomorrow!! ICSSI Check out the program: icssi.org

There is a lot not to like about AI, but it can also be very helpful. In a recent @nature world view Dashun Wang explains how AI could be used to maximize the impact of research nature.com/articles/d4158…

I enjoyed presenting at the ICSSI today. I hope the questions I posed will help to inspire new research to better inform policymakers & drive important #SciPol decisions. #ICSSI

.Jian Gao and Dashun Wang develop a measure framework which demonstrates the widespread use and benefits of AI in science. Nonetheless, there is a substantial gap between AI education and application across disciplines. CSSI Kellogg School nature.com/articles/s4156…

AI won two Nobel prizes this week. What exactly is the impact of #AI on science? Check out our latest paper, just published in Nature Human Behaviour: Quantifying the use and potential benefits of artificial intelligence in scientific research rdcu.be/dWEYb Key takeaways:

Releasing an open dataset based on Michaël Bikard's dissertation regarding "idea twins." David Hsu and I scaled up his algorithm to the entire Web of Science, scraping Google Scholar to detect adjacent co-citation in PDFs. Here's the server farm in my basement 1/

New year --> new adventures! Next quarter Stanford Graduate School of Business I’m thrilled to be teaching a PhD seminar on “Theoretical Computational Social Science.” We will explore the possibility of shifting away from a methods-based definition of CSS to one grounded in a unifying theoretical

We are adding predocs into our intellectual mix!! This will be a very unique opportunity, where the predocs will thrive in a collaborative interdisciplinary environment, gaining critical skills. Key areas: LLMs, innovation, networks. JOIN US!!!

Kellogg is launching the Northwestern Innovation Institute with a $25M gift from Pin Ni and Future Wanxiang Foundation! The institute will examine how innovation occurs across science, technology, and business. Learn more in the full news story: kell.gg/ke9a

🚨 Our latest paper is out today in Science! We uncover stark and systematic partisan differences in the amount, content, and character of science used in policy, which mirror differences in political elites’ trust in science. Four years in the making. Led by Zander Furnas 1/n

🚨New paper🚨 Excited to share our latest on nature today: The PIVOT PENALTY in research. nature.com/articles/s4158… More than five years in the making. Key finding: The impact of new research steeply declines the further a researcher moves from their previous work.

Check out our latest paper in nature, where we ask a simple question: What happens when researchers pivot? The answer is deceptively simple: pivot penalty. See thread by Yian Yin on the paper. Great collaboration with Ryan Hill, Carolyn Stein, Xizhao Wang, & Ben Jones

Academics’ research-publication patterns shift fundamentally after they attain tenure, a coveted status that provides job security in the United States, according to an analysis1 of more than 12,000 researchers across 15 disciplines. go.nature.com/4lL1onP

I’m happy to announce our next i3open - the Innovation Information Initiative Upskilling session, Thursday August 21 at noon (New York time / EDT). By far, our most requested topic was Large Language Models, so I’m excited that I was able to enlist Navid Asgari (Fordham) and his coauthor Deepak Nayak (OSU) for this
