So in 2007, physicists wrote a paper that made the headlines: according to their calculations, human coin flips arenā€™t 50/50 - more like 51/49. Why is that, and did students in Amsterdam really flip 350,000 coins to find out? šŸ§µ

Iā€™m very excited to share that my graduate work is now online in @ScienceMagazine today! With generous help from my mentor @yuji_ikegaya and my amazing teammates, we investigated a top-down pathway for volitional heart rate regulation! science.org/doi/10.1126/scieā€¦

Top-down brain circuits for operant bradycardia

Heart rate (HR) can be voluntarily regulated when individuals receive real-time feedback. In a rat model of HR biofeedback, the neocortex and medial forebrain bundle were stimulated as feedback and...

All-day AR would benefit from AI models that understand a person's context & eye tracking could be key for task recognition. Yet past work - including our own research.facebook.com/publicā€¦ - hasn't found much added value from gaze in addition to computer vision & egocentric video 2/

Can Gaze Inform Egocentric Action Recognition? - Meta Research

We investigate the hypothesis that gaze-signal can improve egocentric action recognition on the standard benchmark, EGTEA Gaze dataset.

New paper alert! @RealityLabs Eye gaze in everyday life contains multi-scale temporal dependencies across objects (1-7 fixations into past, depending on task). Akin to natural language. Key to foundation models for visual understanding in mixed reality dl.acm.org/doi/10.1145/36499ā€¦

But object-part-based image segmentation is just starting to gain traction, and universal segmentation (segmenting and labelling all image pixels) is still a challenge. So this is one major bottleneck for aligning the model input state space with that of human active vision. 5/

Once the input state space is well-aligned with human action & vision, and appropriate models that can represent long-term dependencies are used, we believe that multiple problems in contextual AI may be solved convergently by a single (gaze-based) visual foundation model. 6/
