I'll be giving a talk on building, training, and finetuning LLMs in the ACM Tech Talks series on Wed at 1 pm ET. Put together a nice (and hopefully informative) slide deck, and now really look forward to it! The talk is free to attend!
Calling PhD Econ students (especially current 3th-4th years in PA, NJ, DE, MD) -- apply to our mentoring week in September. Applications due June 21!
The Philadelphia Fed Mentoring & Advancing PhDs Program is a unique opportunity for PhD candidates to connect with like-minded scholars in economics and finance. Apply to join us this fall for a week of interaction, feedback, and mentorship. bit.ly/3vqnSWp
Hmm..I don't use the platform much but why does it show posts from people I don't follow. Did they change it recently??
Excited to share our latest research: The myth of cosmopolitan cities: Why large urban areas are more segregated Long-standing assumption is that large cities with their diverse population, foster diverse person-to-person interactions. Our @Nature paper shows the opposite is…
Visualizing the embedding space for models from @huggingface Hub using @nomic_ai's Atlas tool and @JinaAI_ embeddings. 🧵 Check out the overall embedding map! Clear clusters emerge, along with intriguing outliers. Let's dive into this exploration!
I am truly grateful to have this dissertation committee @peterpaws @mrfrank5790 @HeDaqing @zpardos
Congratulations to Hung Chau Kim who successfully defended his PhD thesis today @PittDINS @SciPitt on Explainable Course Recommendation: Connecting College Education to Future Careers Through Skills - time to celebrate with thesis committee members calendar.pitt.edu/event/explaina…
Attending Hung Chau’s PhD defence @PittTweet on “Explainable Course Recommendation: Connecting College Education to Knowledge and Careers Through Skills” Very interesting work in the intersection of #Recsys & #Education Congratulations Dr. @hungkchau🎓 journals.plos.org/plosone/articl…
Defending his way to a PhD! Nice work @hungkchau ! Learn more about his work on college-taught skills and post-graduation earnings: journals.plos.org/plosone/articl…
This is huge: Llama-v2 is open source, with a license that authorizes commercial use! This is going to change the landscape of the LLM market. Llama-v2 is available on Microsoft Azure and will be available on AWS, Hugging Face and other providers Pretrained and fine-tuned…
Calling all computational social scientists! 🤓 #Postdoc position available at @PittDINS with Prof. @rhodiuslin Apply complex network and socio-cognitive theories to social dynamics & conflicts in social networks. forms.gle/juZ2rjxKjJdCtV…
Do we really need multilingual models? 🤔 We show that, with some tricks, translate-test (machine translating the input into English and using an English model) can work better than previously reported, outperforming multilingual models in most tasks 🤯 arxiv.org/abs/2305.14240
Random note on k-Nearest Neighbor lookups on embeddings: in my experience much better results can be obtained by training SVMs instead. Not too widely known. Short example: github.com/karpathy/rando… Works because SVM ranking considers the unique aspects of your query w.r.t. data.

I believe there will be a lot of exciting work following this. I have learned a lot throughout this project from you both @SarahHBana and @mrfrank5790
Excited to share this research! @mrfrank5790 and I usually study skills from the demand side. In this paper, led by exceptional Pitt grad student @hungkchau, we look at university syllabi and the skills they teach.
New @PLOSONE paper w/ @SarahHBana @hungkchau and Baptiste Bouvier! Workers' skills determine earnings, migration, and careers, but where do those skills come from? Using millions of college syllabi from @opensyllabus we create skill profiles for majors and universities
Two good news in two days - another paper "Knowledge Annotation for Intelligent Textbooks", is now assigned to a a journal issue - i.e., officially published. Congrats to @PittDINS and @ISPPitt team - @khushsi @hungkchau @HeDaqing & Mengdi Wang link.springer.com/article/10.100…
DINS assistant professor, Dr. Morgan Frank @mrfrank5790 is giving a talk tomorrow at our friends down the street at @CarnegieMellon on his research on skill complexity and the future of work. More info: halley.exp.sis.pitt.edu/comet/presentC…

Our amazing AI and ranking team just pushed a new ranker that now incorporates not just semantics, string matching, etc. but also popularity of answers and hence brings way more and better results, eg. a coding question a la you.com/search?q=how%2…
