🎭 Most facial expression editors rely on fixed emotion categories, limiting realism and nuance. 🎙️ In this WiAIR episode, we speak with Dr. Angelica Lim @petitegeek.bsky.social‬ about “EmoStyle,” a method that enables fine-grained emotional edits using continuous parameters! (1/10)

Dear ChatGPT, Am I the Asshole? While Reddit users might say yes, your favorite LLM probably won’t. We present Social Sycophancy: a new way to understand and measure sycophancy as how LLMs overly preserve users' self-image.

Excited to dig into this. In the first couple of pages it talks about features of real world interactions that are usually filtered out of text-based systems (e.g. pauses, huh?, um, uh). Thanks @mzmttks.bsky.social for the recommendation!

This is fantastic work by @milesklee.bsky.social documenting the way ChatGPT can cause users’ mental health to deteriorate quickly into catastrophic delusions. This technology never should have been released to the public and that was obvious from day 1 www.rollingstone.com/culture/cult...

New video! Can a gadget really detect your level of stress? When your heart pounds hard in your chest, what does it mean psychologically? It depends. Your everyday experience is constructed from interacting signals inside and outside you, an idea called "relational meaning." youtu.be/mpRoxR81lSU

In the wake of the Lapu Lapu tragedy here in Vancouver, I'm dedicating my sabbatical year to applying my AI background to pushing forward psychosis research. Some thoughts 👇

Environments where robots can be helpful (forest fires, construction sites) are really loud. We'll need more ways to interact with robots other than verbal language. - Prof. Julie Adams @hri-conference.bsky.social

My PhD student Akhila's been doing some incredible cultural work in the last few years! Check out out latest work on cultural safety and hand gestures, showing most vision and/or language AI systems are very cross-culturally unsafe!

I'm excited to share my first registered report on social interactions in @journalautism.bsky.social! Our study explores how social motor synchrony – the natural mirroring of movements – impacts rapport between autistic, neurotypical, and mixed dyads. Thread 👇 journals.sagepub.com/doi/10.1177/...

Clever study that explores the debate between those who claim that color categories are 'innate' and those who argue that they are dependent on language. It turns out that monkeys, unlike humans, do not have consensus color categories, suggesting cognitive mechanisms such as language are required.🧪🧠

New podcast episode where I use philosophy of empathy to explore the double empathy problem, considering where it applies and how it relates to neurodiversity. This is a new recording of my presentation I gave at Tilburg last month #autism #philmed #doubleempathyproblem

Student was surprised to go from 50% on their midterm to 80% on the final. Said they used ChatGPT to quiz them before the final 🤔 Underrated use case is using LLMs to ask us good questions, to make us think, instead of "think" for us.
