Robust Sparse Voting
Rachid Guerraoui, Youssef Allouah, Oscar Jean Olivier Villemaud, Le Nguyen Hoang
Many applications, such as content moderation and recommendation, require reviewing and scoring a large number of alternatives. Doing so robustly is however very challenging. Indeed, voters' inputs are inevitably sparse: most alternatives are only scored b ...
2024Predicting party switching through machine learning and open data
Silvestro Micera, Emanuele Rossi
Parliament dynamics might seem erratic at times. Predicting future voting patterns could support policy design based on the simulation of voting scenarios. The availability of open data on legislative activities and machine learning tools might enable such ...
CELL PRESS2023Object Priors for Volumetric Image Segmentation
Pamuditha Udaranga Wickramasinghe
Large training datasets have played a vital role in the success of modern deep learning methods in computer vision. But, obtaining sufficient amount of training data is challenging, specially when annotating volumetric images. This is because fully annotat ...
EPFL2022Auditing the Swiss Post E-voting System: An Architectural Perspective
Switzerland is one of the few countries globally that has a national program for electronic voting (E-voting), which has been evolving in several stages for well over a decade. For the past several years, the program’s most recent stage has focused on intr ...
2022Self-Attentive Spatial Adaptive Normalization for Cross-Modality Domain Adaptation
Jean-Philippe Thiran, Guillaume Marc Georges Vray, Devavrat Tomar, Manana Lortkipanidze
Despite the successes of deep neural networks on many challenging vision tasks, they often fail to generalize to new test domains that are not distributed identically to the training data. The domain adaptation becomes more challenging for cross-modality m ...
2021Empirical Evidence on the Effectiveness of Shareholder Democracy
This thesis is composed of two essays that study the effectiveness of shareholder democracy.
In the first essay, I analyze the firm value implications of shareholder-initiated proposals. I show that managerial resistance precludes half of shareholder-init ...
EPFL2021The probability of intransitivity in dice and close elections
We study the phenomenon of intransitivity in models of dice and voting. First, we follow a recent thread of research for n-sided dice with pairwise ordering induced by the probability, relative to 1/2, that a throw from one die is higher than the other. We ...
2020The Distortion of Distributed Voting
Voting can abstractly model any decision-making scenario and as such it has been extensively studied over the decades. Recently, the related literature has focused on quantifying the impact of utilizing only limited information in the voting process on the ...
SPRINGER INTERNATIONAL PUBLISHING AG2019The geographic evolution of political cleavages in Switzerland: A network approach to assessing levels and dynamics of polarization between local populations
Scholarly studies and common accounts of national politics enjoy pointing out the resilience of ideological divides among populations. Building on the image of political cleavages and geographic polarization, the regionalization of politics has become a tr ...
2018General Surface Energy for Spinal Cord and Aorta Segmentation
Michaël Unser, Daniel Andreas Schmitter, Virginie Sophie Uhlmann, Harshit Gupta
We present a new surface energy potential for the segmentation of cylindrical objects in 3D medical imaging using parametric spline active contours (a.k.a. spline-snakes). Our energy formulation is based on an optimal steerable surface detector. Thus, we c ...
