Communication impacting financial markets
Jorgen Vitting Andersen, Ioannis Vrontos, Petros Dellaportas +1
Behavioral finance has become an increasingly important subfield of finance. However the main parts of behavioral finance, prospect theory included, understand financial markets th…
Equilibria of Plurality Voting: Lazy and Truth-biased Voters
Edith Elkind, Evangelos Markakis, Svetlana Obraztsova +1
We present a systematic study of Plurality elections with strategic voters who, in addition to having preferences over election winners, have secondary preferences, which govern th…
Interference Functionals in Poisson Networks
Udo Schilcher, Stavros Toumpis, Martin Haenggi +3
We propose and prove a theorem that allows the calculation of a class of functionals on Poisson point processes that have the form of expected values of sum-products of functions.…
Cooperative Games with Overlapping Coalitions: Charting the Tractability Frontier
Yair Zick, Georgios Chalkiadakis, Edith Elkind +1
In many multiagent scenarios, agents distribute resources, such as time or energy, among several tasks. Having completed their tasks and generated profits, task payoffs must be div…
Homogenization of random elliptic systems with an application to Maxwell's equations
G. Barbatis, I. G. Stratis, A. N. Yannacopoulos
We study the homogenization of elliptic systems of equations in divergence form where the coefficients are compositions of periodic functions with a random diffeomorphism with stat…
Generating Natural Language Descriptions from OWL Ontologies: the NaturalOWL System
Ion Androutsopoulos, Gerasimos Lampouras, Dimitrios Galanis
We present NaturalOWL, a natural language generation system that produces texts describing individuals or classes of OWL ontologies. Unlike simpler OWL verbalizers, which typically…
Essential spectral equivalence via multiple step preconditioning and applications to ill conditioned Toeplitz matrices
D. Noutsos, S. Serra-Capizzano, P. Vassalos
In this note, we study the fast solution of Toeplitz linear systems with coefficient matrix , where the generating function is nonnegative and has a unique zero at zero…
Efficient Proactive Caching for Supporting Seamless Mobility
Vasilios A. Siris, Xenofon Vasilakos, George C. Polyzos
We present a distributed proactive caching approach that exploits user mobility information to decide where to proactively cache data to support seamless mobility, while efficientl…
From advertising profits to bandwidth prices-A quantitative methodology for negotiating premium peering
Laszlo Gyarmati, Nikolaos Laoutaris, Kostas Sdrolias +2
We have developed a first of its kind methodology for deriving bandwidth prices for premium direct peering between Access ISPs (A-ISPs) and Content and Service Providers (CSPs) tha…
Model-based clustering using copulas with applications
Ioannis Kosmidis, Dimitris Karlis
The majority of model-based clustering techniques is based on multivariate Normal models and their variants. In this paper copulas are used for the construction of flexible familie…
Text Relatedness Based on a Word Thesaurus
George Tsatsaronis, Iraklis Varlamis, Michalis Vazirgiannis
The computation of relatedness between two fragments of text in an automated manner requires taking into account a wide range of factors pertaining to the meaning the two fragments…
