The App Store moment for decentralized AI is here! We're excited to launch Flower Hub with apps from @Sony, @mozilla, @OwkinScience, and more.

The boundary between reality and the virtual world is about to disappear.
Imagine characters from Pokemon or Digimon coming to life—not on a screen, but right in front of you. You reach out, and they respond.

Introducing X1.
The first real-time interactive video model that brings imagination into reality.
Built by the Xmax AI team from Tsinghua University.

Let’s Play the World through AI.

Repost & comment to join the X1 private beta (free).

How did we get here? In real-time discussions, ideas get lost and conversations drift. EchoMind is a human-AI facilitation tool that organizes discussions into live issue maps, keeping teams focused and productive. ✅story, video & code #CSCW2025 @ACM_CSCW https://t.co/8Owi2GjkHg

This work marks a milestone in developing a more comprehensive and nuanced understanding of human actions. Our two IMWUT papers have demonstrated that Human Activity Recognition (HAR) provides crucial context for richer semantic action understanding, both in ages of DL and LLMs.

Congrats to #Tsinghua University's Pervasive HCI Lab @thuhci & West China Hospital's @IHuaXi Rehab Medicine Center for winning the #IMWUT Distinguished Paper Award at #UbiComp2025 for "UbiPhysio"! 🏆Their innovative study combines biomech with LLMs to deliver home rehab guidance.

[Weihao Chen 陈伟浩 @AtomieChen]

First time @ubicomp, presenting and demoing RingMind: our lab-built smart ring (mic+IMU) + LLMs to understand speech & gesture in natural settings. A step toward human-AI cognitive alignment through multimodal interfaces.

Next: CSCW sharing EchoMind and excited to connect!

Prof. Chen Ning Yang, a world-renowned physicist, Nobel Laureate in Physics, Academician of the Chinese Academy of Sciences, Professor at Tsinghua University, and Honorary Director of the Institute for Advanced Study at Tsinghua University, passed away in Beijing due to illness at the age of 103. His life stands as a timeless chapter in human history—one that shines not only for China but for the global community of thinkers and innovators. His legacy will live on forever.

I thank all the collaborators and our peers. This is a milestone for myself as an HCI4Health researcher.

"The first AGI will be Federated" -- come hear my keynote at the @AcmSensys conference this Wednesday morning. I'll explain why when we finally achieve AGI, and flick the switch to bring it online, it will have been trained using some variety of federated AI. And not the training methods of today, DDP and the like, that are limited to being deployed in single data centers -- which are themselves fast reaching the limits of their own scalability as we struggle to co-locate and power north of 100k GPUs in one physical place.

In support of my talk, here is a preview of a few results coming in hot from a new arxiv paper produced by @flwrlabs and @CaMLSys (@Cambridge_Uni) that will go live also Wednesday. We show our unique approach and system (aka Photon built on Flower) produces LLMs that are both better (by perplexity) and faster to train than DDP (when network speeds are equal, as measured up to 7B). Furthermore, we show this can scale effectively as we add more weakly connected GPUs -- while also being more efficient (eg better wall clock training times) than any existing known methods for training under decentralized/widely-distributed settings.

Folks, it's time to train different. Larger and more complex LLM settings are underway. Link to arxiv Wednesday.

Presented my first #CHI2024 paper today! I was thrilled to receive warm reactions from the audiences. For sure, PepperPose shall open a new route for future interactions driven by human actions. The goal is to waive users from wearing devices and allows them to move/act freely.🙂

[Chongyang Wang @mvrjustid]

lovely!

First day at #CHI2024 in Hawaii! 🌴🌺
@thuhci team is excited to be here~🎉
Today, we had a great time meeting with some amazing HCI pioneers (Jussi P. P. Jokinen from University of Jyväskylä during, and Neha Kumar @nehakumar )! 📸✨

Flower is connecting with it's global community today: 🇰🇷🇪🇸🇩🇪🇨🇳🇬🇧🇫🇷🇺🇸🇮🇳... and many more! And most importantly, we are doing it with a zero carbon 👣foot print. 😎

[Chongyang Wang @mvrjustid]

Our lines of research shall meet shortly in the near future, AI-powered service needs FL-backed cloud computing 😎
