🤯NeurIPS 2025 might break records as the most submitted-to academic conference ever. One of our submission IDs is already ~23,000 — final count could hit 30,000. Absolute madness. #NeurIPS2025 #AI
take a year out of your life and read these two textbooks cover-to-cover. you will already know more than 90% of people in AI
#ICLR2025 Thrilled to share that our @iclr_conf paper has been accepted for an oral presentation! We show that LLMs represent political ideologies on a linear axis—and that we can detect and even steer their ideological perspectives. In our paper: - We find a linear "map" of political ideologies within LLM activation space, where U.S. politicians and news outlets are positioned along a left-right spectrum. - By probing this activation space, we can measure the political perspective that LLMs implicitly adopt as they generate text, token by token. - By directly intervening in the activation space, we can steer the model’s output toward more left- or right-leaning perspectives—like turning a dial. Huge thanks to the amazing collaborators and mentors, @profjamesevans and @AaronSchein! 🔗 Full paper: openreview.net/pdf?id=rwqShzb…
Because we're better data scientists than the ppl teaching "data science" courses Data science tends to be taught by ppl in stats and applied math departments, who develop tools but spend little time using them, so you learn little about actually doing applied data science
