Conflict Solution According to "Aggressiveness" of Agents in Floor-Field-Based Model
Pavel Hrabák, Marek Bukáček
This contribution introduces an element of "aggressiveness" into the Floor-Field based model with adaptive time-span. The aggressiveness is understood as an ability to win conflict…
Influence diagrams for the optimization of a vehicle speed profile
Václav Kratochvíl, Jiří Vomlel
Influence diagrams are decision theoretic extensions of Bayesian networks. They are applied to diverse decision problems. In this paper we apply influence diagrams to the optimizat…
Bayesian Network Models for Adaptive Testing
Martin Plajner, Jiří Vomlel
Computerized adaptive testing (CAT) is an interesting and promising approach to testing human abilities. In our research we use Bayesian networks to create a model of tested humans…
The limiting shape of a full mailbox
M. Formentin, J. M. Swart
We study a model for email communication due to Gabrielli and Caldarelli, where someone receives and answers emails at the times of independent Poisson processes with intensities $…
Gold, currencies and market efficiency
Ladislav Kristoufek, Miloslav Vosvrda
Gold and currency markets form a unique pair with specific interactions and dynamics. We focus on the efficiency ranking of gold markets with respect to the currency of purchase. B…
Pathwise duals of monotone and additive Markov processes
Anja Sturm, Jan M. Swart
This paper develops a systematic treatment of monotonicity-based pathwise dualities for Markov processes taking values in partially ordered sets. We show that every Markov process…
A sharp interface evolutionary model for shape memory alloys
Hans Knüpfer, Martin Kružík
We show the existence of an energetic solution to a quasistatic evolutionary model of shape memory alloys. Elastic behavior of each material phase/variant is described by polyconve…
Adaptive Multiple Importance Sampling for Gaussian Processes
Xiaoyu Xiong, Václav Šmídl, Maurizio Filippone
In applications of Gaussian processes where quantification of uncertainty is a strict requirement, it is necessary to accurately characterize the posterior distribution over Gaussi…
Local bilinear multiple-output quantile/depth regression
Marc Hallin, Zudi Lu, Davy Paindaveine +1
A new quantile regression concept, based on a directional version of Koenker and Bassett's traditional single-output one, has been introduced in [Ann. Statist. (2010) 38 635-669] f…
Business cycle synchronization within the European Union: A wavelet cohesion approach
Lubos Hanus, Lukas Vacha
In this paper, we map the process of business cycle synchronization across the European Union. We study this synchronization by applying wavelet techniques, particularly the cohesi…
The Brownian web, the Brownian net, and their universality
Emmanuel Schertzer, Rongfeng Sun, Jan M. Swart
The Brownian web is a collection of one-dimensional coalescing Brownian motions starting from everywhere in space and time, and the Brownian net is a generalization that also allow…
Perfect plasticity with damage and healing at small strains, its modelling, analysis, and computer implementation
Tomáš Roubíček, Jan Valdman
The quasistatic, Prandtl-Reuss perfect plasticity at small strains is combined with a gradient, reversible (i.e. admitting healing) damage which influences both the elastic moduli…
Polyhedral aspects of score equivalence in Bayesian network structure learning
James Cussens, David Haws, Milan Studeny
This paper deals with faces and facets of the family-variable polytope and the characteristic-imset polytope, which are special polytopes used in integer linear programming approac…
Estimation of Zero Intelligence Models by L1 Data
Martin Šmíd
A unit volume zero intelligence (ZI) model is defined and the distribution of its L1 process is recursively described. Further, a generalized ZI (GZI) model allowing non-unit marke…
Non-parametric Bayesian Models of Response Function in Dynamic Image Sequences
Ondřej Tichý, Václav Šmídl
Estimation of response functions is an important task in dynamic medical imaging. This task arises for example in dynamic renal scintigraphy, where impulse response or retention fu…
Power-law correlations in finance-related Google searches, and their cross-correlations with volatility and traded volume: Evidence from the Dow Jones Industrial components
Ladislav Kristoufek
We study power-law correlations properties of the Google search queries for Dow Jones Industrial Average (DJIA) component stocks. Examining the daily data of the searched terms wit…
Can the bivariate Hurst exponent be higher than an average of the separate Hurst exponents?
Ladislav Kristoufek
In this note, we investigate possible relationships between the bivariate Hurst exponent and an average of the separate Hurst exponents . We show tha…
Decomposition approaches to integration without a measure
Salvatore Greco, Radko Mesiar, Fabio Rindone +1
Extending the idea of Even and Lehrer [3], we discuss a general approach to integration based on a given decomposition system equipped with a weighting function, and a decompositio…
