A Regularization Framework for Mobile Social Network Analysis

Pascal Frossard, Pierre Vandergheynst, Xiaowen Dong

Mobile phone data provides rich dynamic information on human activities in social network analysis. In this paper, we represent data from two different modalities as a graph and functions defined on the vertex set of the graph. We propose a regularization ...

Additive Combinatorics and Discrete Logarithm Based Range Protocols

Rafik Chaabouni, Helger Lipmaa

We show how to express an arbitrary integer interval

I = [0, H]

as a sumset

I = \sum_{i=1}^\ell G_i * [0, u - 1] + [0, H']

of smaller integer intervals for some small values

\ell

,

u

, and

H' < u - 1

, where

b * A = \{b a : a \in A\}

and $A + B = ...

Interval consensus: from quantized gossip to voting

Martin Vetterli, Patrick Thiran, Florence Bénézit

We design distributed and quantized average consensus algorithms on arbitrary connected networks. By construction, quantized algorithms cannot produce a real, analog average. Instead, our algorithm reaches consensus on the quantized interval that contains ...

Social Network Analysis in Multimedia Indexing: Making Sense of People in Multiparty Recordings

Sarah Favre

This paper presents an automatic approach to analyze the human interactions appearing in multiparty data, aiming at understanding the data content and at extracting social informa- tion such as Which role do people play?, What is their attitude?, or Can pe ...

'I pay enough taxes already!' Applying economic voting models to environmental referendums

Philippe Thalmann, Nicholas Bornstein

Objectives. Models of economic voting have rarely been applied to referendum votes. We fill this gap by testing citizens’ voting behavior on environmental policy in relation to their perception of the business cycle. Thus, the study examines the personal, ...

Role Recognition for Meeting Participants: an Approach Based on Lexical Information and Social Network Analysis

Sarah Favre, Alessandro Vinciarelli, Nikhil Garg

This paper presents experiments on the automatic recognition of roles in meetings. The proposed approach combines two sources of information: the lexical choices made by people playing different roles on one hand, and the Social Networks describing the int ...

Sociometry Based Multiparty Audio Recordings Summarization

Alessandro Vinciarelli

This paper shows how Social Network Analysis, the study of relational data in specific social environments, can be used to summarize multiparty radio news recordings. A social network is extracted from each recording and it is analyzed in order to detect t ...

Sociometry Based Multiparty Audio Recordings Segmentation

Alessandro Vinciarelli

This paper shows how Social Network Analysis, the sociological domain studying the interaction between people in specific social environments, can be used to assign roles to different speakers in multiparty recordings. The experiments presented in this wor ...
