🗣️ Last Friday, we had the pleasure of hosting @dustinbwright.com for an insightful talk on “LLMs Lack Perspective and Epistemic Diversity.” The talk explored how diverse are the information and perspectives that people are being exposed to in this new era. #NLProc

We updated our LLM epistemic diversity study with a stronger search baseline closer to true search diversity. It beats every model, even though it is underestimated. In other words, one can expect less information from an LLM vs Google searching. See the new results here! arxiv.org/pdf/2510.04226

News about our epistemic diversity paper! 💻 The code is now a python package! Installation instructions here: github.com/dwright37/ll... 🤗 All 1.6M model responses and 70M clustered claims are now available on HuggingFace! huggingface.co/datasets/dwr... 📄 Paper: arxiv.org/pdf/2510.04226

Our long context summarization dataset is now on 🤗 Huggingface! huggingface.co/datasets/dwr... Use it as a training or a test set for long context query focused summarization! It includes evidence attribution of free-form text spans from the context, making summaries more transparent and reliable!

New preprint: "Unstructured Evidence Attribution for Long Context Query Focused Summarization" We propose *unstructured* evidence attribution for long context summarization and a synthetic dataset called SUnsET which can help models perform this task. Paper link: arxiv.org/abs/2502.14409 Thread ⬇️

📄 New preprint: "Collecting Cost-Effective, High-Quality Truthfulness Assessments with LLM Summarized Evidence" We show: fact checking w/ crowd workers is more efficient when using LLM summaries, quality doesn't suffer. arxiv.org/abs/2501.18265

Happening now @neuripsconf.bsky.social #NeurIPS2024 !!! Come to poster 4003 in East Hall to learn about Bayesian model reduction for structured pruning!

I’m at #NeurIPS2024! I’m also on the faculty job market! Come talk to me about neural network efficiency, reliable NLP, open positions, and come to my spotlight poster on Friday from 11a — 2p in East Exhibit Hall A — C, poster number 4003

"A person who merely refuses to learn what can be known is not a skeptic, but rather an ignoramus; a person who raises questions but does not seek their answers is not a skeptic, but a bullshitter." defector.com/what-the-fuc...

BlueSky starting to feel like my old science focused twitter used to, actually seeing stuff I care about not just drama and politics

Podcasts are a popular medium, but data for computational research is limited! We introduce the Structured Podcast Research Corpus (SPoRC - huggingface.co/datasets/bli...), a large, multimodal dataset of English podcasts 🧵 arxiv.org/abs/2411.07892

Lots of folks listen to podcasts—an estimated half of Americans do monthly!—but there's been limited data to study what happens on them. What do they talk about? Who are the guests? Who is influencing whom?? This new dataset is our attempt to bring light to an important medium
