Mixed feelings about silicon subjects (LLM predictions of human behavior) as replacements for human subjects? Consider the mixed subjects design. 🚨Now published at Sociological Methods and Research🚨 doi.org/10.1177/004912…
📢 Our paper "AI safety for everyone" is out at Nature Machine Intelligence @NatMachIntell . We challenge the narrative that AI safety is primarily about minimizing existential risks from AI. Why does this matter? A 🧵
Meet Ai2 Paper Finder, an LLM-powered literature search system. Searching for relevant work is a multi-step process that requires iteration. Paper Finder mimics this workflow — and helps researchers find more papers than ever 🔍
Paper day: Led by the one and only @rozanski_t, we conducted a painstakingly detailed study on scaling spectral emulations with Transformers. We learned how to optimally predict the number of training samples needed in balance with model size and hyperparameter choices. The…
Check out our latest paper! We test different strategies and models for prompting and fine tuning LLMs to perform stance classification tasks. dl.acm.org/doi/10.1145/37…
Excited to share our latest research, published in PNAS Nexus! 🌍 w/ @balietti, @spfraib , @AncaBalietti 📄academic.oup.com/pnasnexus/adva… #ClimateChange #ScienceCommunication #ClimateAction
In this Perspective, Dörr et al. argue that research on social media has mainly focused on anti-social behaviours and call for more research on the ways in which social media platforms can empower pro-social behaviour. nature.com/articles/s4156…
We test the relationship b/w multiple historical cultural patterns & modern-day language using #NLProc across two countries (China & Japan) & two social media platforms (Weibo & Twitter). Paper out in @HSScomms! nature.com/articles/s4159… Summary thread by @ThomasTalhelm 🔽
