Augmented proximity: Integration of physical and virtual proximity to enhance network connectivity

Mi Chang, Ji-Hyun Lee, Barbara Guidi
2021 PLoS ONE  
The results show that one of the two services has a higher taxonomy-based value, and a reasonable basis for selecting one based on proximity is established.  ...  With the continuing increase in online communications, virtual proximity as well as physical proximity has become a common way to connect individuals.  ...  For example, we have a restaurant that needs publicity.  ...

A Framework to Explore Proximate Human-Robot Coordination

Sachiko Matsumoto, Auriel Washburn, Laurel D. Riek
2022 ACM Transactions on Human-Robot Interaction (THRI)  
Research in this area draws from a wide variety of other fields, from human-human interaction to control theory, making study design complex, particularly for those outside the field of HRI.  ...  Proximate human-robot teaming (pxHRT) is a complex subspace within human-robot interaction.  ...  We thank the Toyota Research Institute and Air Force Oice of Scientiic Research (AFOSR) for supporting this work under Grant No. FA9550-18-1-0125.  ...

Proximity of black hole horizons: Lessons from Vaidya spacetime

Ivan Booth, Jonathan Martin
2010 Physical Review D  
In this paper we propose a geometrical measure of the distance between those horizons and investigate it for the case of the Vaidya spacetime.  ...  We show that it is well-defined, physically meaningful, and has the expected behaviour in the near-equilibrium limit. We consider its implications for our understanding of black hole physics.  ...  Acknowledgments We would like to thank Michal Heller for his useful comments. I. B. was supported by the Natural Sciences and Engineering Council of Canada.  ...

Proximity Sensor for Thin Wire Recognition and Manipulation

Andrea Cirillo, Gianluca Laudante, Salvatore Pirozzi
2021 Machines  
In this work the authors propose a Time-of-Flight pre-touch sensor, integrated with a previously designed tactile sensor, for an accurate estimation of thin wire pose and shape.  ...  In such applications, a vision-based system could not be enough to obtain accurate pose and shape estimation.  ...  The funders had no role in the design of the study; in the collection, analyses, or interpretation of data; in the writing of the manuscript, or in the decision to publish the results.  ...

Block-Coordinate Proximal Algorithms for Scale-Free Texture Segmentation

Barbara Pascal, Nelly Pustelnik, Patrice Abry, Jean-Christophe Pesquet
2018 2018 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)  
The present contribution aims to investigate the potential of recent blockcoordinate dual and primal-dual proximal algorithms for overcoming this numerical issue.  ...  Our study shows that a key ingredient in the success of the proposed block-coordinate approaches lies in the design of the blocks of variables which are updated at each iteration.  ...  In addition, the lattice splitting developed here leads to a significant acceleration of the dual forward-backward algorithm for TV denoising.  ...

Wasserstein Proximal of GANs [article]

Alex Tong Lin, Wuchen Li, Stanley Osher, Guido Montufar
2021 arXiv   pre-print
We introduce a new method for training generative adversarial networks by applying the Wasserstein-2 metric proximal on the generators. The approach is based on Wasserstein information geometry.  ...  We obtain easy-to-implement iterative regularizers for the parameter updates of implicit deep generative models.  ...  This saves us the need to compute the matrix G and its inverse explicitly. As we will show, the Wasserstein metric can be translated to practical proximal methods for implicit generative models.  ...
