How do we reliably judge if AI companions are performing well on subjective, context-dependent, and deeply human tasks? 🤖
Excited to share the first paper from my postdoc (!!) investigating when LLMs are reliable judges - with empathic communication as a case study 🧐

When are LLMs-as-judge reliable?
That's a big question for frontier labs and it's a big question for computational social science.
Excited to share our findings (led by @aakriti1kumar.bsky.social!) on how to address this question for any subjective task & specifically for empathic communications

Looking forward to @maxkreminski.bsky.social speaking @nicoatnu.bsky.social tomorrow!
It’s notoriously difficulty to evaluate interfaces intended to support creative work. This Wednesday, NICO is thrilled to host @maxkreminski.bsky.social from Midjourney to discuss: "Tracing and Shaping Paths in Design Space". #WedatNICO #AI

What is perception? What do we really see when we look at the world?
And, why does the amodal completion illusion lead us to see a super long reindeer in the image on the right?
This week @chazfirestone.bsky.social joined the NU CogSci seminar series to address these fundamental questions

2024 marks the official launch of the Human-AI Collaboration Lab, so I wrote a one page letter to introduce the lab, share highlights, and begin a lab tradition of reflecting on the year and sharing what we're working on in an easy to digest annual letter to share with friends and colleagues.

Real vs. fake: Can you spot AI-generated images?
Some images generated by artificial intelligence have become so convincingly real that there is no surefire way to spot the fakes. But experts say there are still things we can try to detect fakes.

This paper explores how language shapes behavior. Our contribution, however, is not in testing specific hypotheses- its in generating them (using #LLMs + #ML + #BehSci)
But how exactly?

The ability for thoughtful people to spot AI-generated poetry in a couple seconds vs. the study's participants reveals classic problems inherent to Imitation Game research:
Lack of domain expertise & lack of knowledge of AI's capabilities and limitations -> falling for & even preferring simulacra

Why does ChatGPT outperform physicians + ChatGPT in this clinical vignette study?
User error seems to be the culprit
If users don't know how to interact with the technology (however easy it may seem), then the experiment misses out on what would happen if participants had basic knowledge LLMs
