Excited to share our paper, Substance over Style: Evaluating Proactive Conversational Coaching Agents, accepted to ACL 2025 Main Track! LLMs do well when given clear context up front. But what if that context doesn't exist yet? (1/5) 🔗Read more: arxiv.org/abs/2503.19328

Most complex tasks feature ill- and underdefined goals, at least initially. Check out Vidya Srinivas's paper demonstrating that agents need to do a lot more than follow instructions, incl. refining goals, and balance competing objectives. Current frontier models fail at these tasks

Let your wearable data "speak" for itself! Introducing SensorLM, a family of sensor-language foundation models trained on ~60 million hours of data, enabling robust wearable data understanding with natural language. → goo.gle/4lSLwQi

Congratulations to Sewon Min for winning yet another dissertation award, this time, ACL dissertation award. So proud of you Sewon!!!

A natural experiment provides evidence for promoting moderate-vigorous physical activity: the importance of walkable cities nature.com/articles/s4158…

A study in nature shows that urban environments that are designed to be easily navigable encourage physical activity. Mobile phone data from the US indicate that average daily steps increase in areas deemed to be more ‘walkable.’ go.nature.com/4mkSUEq

More walking can be a path to better health. A countrywide study by University of Washington #UWAllen professor Tim Althoff, published in nature, found the strongest evidence to date that daily step count is influenced by the built environment. #datascience #PopulationHealth washington.edu/news/2025/08/1…

Nature research paper: Countrywide natural experiment links built environment to physical activity go.nature.com/45eLCfg

These findings provide robust evidence supporting the importance of the built environment in directly improving health-enhancing #physicalactivity and offer potential guidance for public policy activities in this area. nature.com/articles/s4158…
