Articulated objects are common in our daily life. However, current category-level articulation pose works mostly focus on predicting 9D poses on statistical point cloud observations. In this paper, we deal with the problem of category-level online robust ...

Party identification is an important predictor of voting preference, but because a growing percentage of voters do not express any party identification, alternative ways to anticipate voting preferences are required. Partisan slants in voters’ media ...

We investigate the impact of public-spirited voting on the distortion in the metric framework. We employ the public-spirited model proposed by Flanigan et. al. [3] (EC'23) to model the public-spirited behavior of the agents and evaluate the distortion of ...

We study the setting of single-winner elections with ordinal preferences where candidates might be members of alliances (which may correspond to e.g., political parties, factions, or coalitions). However, we do not assume that candidates from the same ...

We investigate efficient ways for the incorporation of liquid democracy into election settings in which voters submit cumulative ballots, i.e., when each voter is assigned a virtual coin that she can then distribute as she wishes among the available ...

The distortion framework in social choice theory allows quantifying the efficiency of (randomized) selection of an alternative based on the preferences of a set of agents. We make two fundamental contributions to this framework.

First, we develop a ...

Online discussion platforms are a vital part of the public discourse in a deliberative democracy. However, how to interpret the outcomes of the discussions on these platforms is often unclear. In this paper, we propose a novel and explainable method for ...

In this paper, we quantify the impact of manipulation using the price of anarchy measurement and study the impact of the lexicographic and the random candidate tie-breaking rules. We show that neither dominates the other in terms of mitigating the impact ...

A voting rule decides on a probability distribution over a set of m alternatives, based on rankings of those alternatives provided by agents. We assume that agents have cardinal utility functions over the alternatives, but voting rules have access to only ...

After the Ethereum DAO attack in 2016, which resulted in significant economic losses, blockchain governance has become a prominent research area. However, there is a lack of comprehensive and systematic literature review on blockchain governance. ...

How do organizational structures influence organizational decision making? This article reveals organizational structures’ dual function: they both (1) aggregate and (2) shape individuals’ decisions. What makes this dual function so remarkable is that the ...

Elections are a special security problem because it is not good enough for systems to be secure and results correct - they must also be verifiably so. Even leaving aside the psychological aspects (some people don’t believe evidence, or don’t understand ...

We study the problem of designing voting rules that take as input the ordinal preferences of n agents over a set of n alternatives and output a single alternative, aiming to optimize the overall happiness of the agents. The input to the voting rule is ...

We give new bounds for the single-nomination model of impartial selection, a problem proposed by Holzman and Moulin (Econometrica, 2013). A selection mechanism, which may be randomized, selects one individual from a group of n based on nominations ...

The emergence of cooperation is a major question in game theory and one under-studied aspect is the effects of networks on the emergent behaviour. My PhD asks this question over multiple collaborations and projects, using methodologies from (evolutionary)...

In this work we propose a family of methods that allow to conjointly compute the reliability of a set of information sources and the reliability of the facts on a set of objects in order to find the truth, by confronting the sources points of view. We ...

Hemaspaandra et al. [6] and Carleton et al. [3, 4] found that many pairs of electoral (decision) problems about the same election system coincide as sets (i.e., they are collapsing pairs), which had previously gone undetected in the literature. While ...

In a district-based election, we apply a voting rule r to decide the winners in each district, and a candidate who wins in a maximum number of districts is the winner of the election. We present efficient sampling-based algorithms to predict the winner ...

When it comes to collective decisions, we have to deal with the fact that agents have preferences over both decision outcomes and how decisions are made. If we create rules for aggregating preferences over rules, and rules for preferences over rules for ...

An abundance of everyday problems rely on voting, ranging from standard political elections and committee decisions to coordinated efforts of multiagent systems. A common and prevalent, yet often underestimated, element of these situations is the ...
