Using “proof of personhood” to tackle social media risks
The ease of creating fake virtual identities plays an important role in shaping the way information — and misinformation — circulates online. Social media platforms are increasingly prominent in shaping public debates, and the tension between online anonym ...
International Risk Governance Center (IRGC)2021Technologizing Democracy or Democratizing Technology? A Layered-Architecture Perspective on Potentials and Challenges
While technology is often claimed to be “democratizing”, the technologizing of society has more often yielded undemocratic or even anti-democratic outcomes. Is technology fundamentally at odds with democracy, or is it merely a rich and infinitely-adaptable ...
University of Chicago Press2021Loops in AdS: from the spectral representation to position space
We compute a family of scalar loop diagrams in AdS. We use the spectral representation to derive various bulk vertex/propagator identities, and these identities enable to reduce certain loop bubble diagrams to lower loop diagrams, and often to tree- level ...
2020A dashboard for controlling polarization in personalization
Nisheeth Vishnoi, Laura Elisa Celis, Farnood Salehi, Vijay Keswani, Sayash Kapoor
Personalization is pervasive in the online space as it leads to higher efficiency for the user and higher revenue for the platform by individualizing the most relevant content for each user. However, recent studies suggest that such personalization can lea ...

Personalization is pervasive in the online space as it leads to higher efficiency for the user and higher revenue for the platform by individualizing the most relevant content for each user. However, recent studies suggest that such personalization can lea ...
ASSOC COMPUTING MACHINERY2019Collapse phenomena of deformed cavitation bubbles
Cavitation bubbles are a topic of long-standing interest owing to the powerful phenomena associated with their collapse. Their unique ability to focus energy typically causes damage in hydraulic machinery (turbines, pumps, propellers, ...) but, if managed ...
EPFL2017PEN recsys: a Personalized News Recommender Systems Framework
Boi Faltings, Florent Frédéric Garcin
We present the Personalized News (PEN) recommender systems framework, currently in use by a newspaper website to evaluate various algorithms for news recommendations. We briefly describe its system architecture and related components. We show how a researc ...
2013PEN recsys: a Personalized News Recommender Systems Framework (DEMO)
Boi Faltings, Florent Frédéric Garcin
We present the Personalized News (PEN) recommender systems framework, (Note that this paper is an extended abstract of Garcin2013b), currently in use by a newspaper website to evaluate various algorithms for news recommendations. We briefly describe its sy ...
2013A MATLAB-based tool for visualizing the plane wave propagation in multilayer structures containing metamaterials
The paper reports on a graphical user interface developed in MATLAB to aid the visualization of the plane wave impinging from a lossless half-space onto a multilayer structure. Individual layers are assumed to be homogeneous and isotropic with electric per ...
2012Concurrent polarization retrieval in multiheterodyne scanning near-field optical microscopy: validation on silicon formbirefringent grating
Hans Peter Herzig, Vincent Paeder, Libo Yu, Tristan Sfez
We demonstrate a concurrent polarization-retrieval algorithm based on a multi-heterodyne scanning near-field optical microscopy (MHSNOM) measurement system. This method relies on calibration of the polarization properties of the MH-SNOM using an isotropic ...
