A Strong Order 1/2 Method for Multidimensional SDEs with Discontinuous Drift
Gunther Leobacher, Michaela Szölgyenyi
In this paper we consider multidimensional stochastic differential equations (SDEs) with discontinuous drift and possibly degenerate diffusion coefficient. We prove an existence an…
Modeling Styles in Business Process Modeling
Jakob Pinggera, Pnina Soffer, Stefan Zugal +5
Research on quality issues of business process models has recently begun to explore the process of creating process models. As a consequence, the question arises whether different…
Tying Process Model Quality to the Modeling Process: The Impact of Structuring, Movement, and Speed
Jan Claes, Irene Vanderfeesten, Hajo A. Reijers +7
In an investigation into the process of process modeling, we examined how modeling behavior relates to the quality of the process model that emerges from that. Specifically, we con…
Fitting High-Dimensional Interaction Models with Error Control
Kory D. Johnson, Robert A. Stine, Dean P. Foster
There is a renewed interest in polynomial regression in the form of identifying influential interactions between features. In many settings, this takes place in a high-dimensional…
A recursive algorithm for multivariate risk measures and a set-valued Bellman's principle
Zachary Feinstein, Birgit Rudloff
A method for calculating multi-portfolio time consistent multivariate risk measures in discrete time is presented. Market models for assets with transaction costs or illiquidit…
A Parametric Simplex Algorithm for Linear Vector Optimization Problems
Birgit Rudloff, Firdevs Ulus, Robert Vanderbei
In this paper, a parametric simplex algorithm for solving linear vector optimization problems (LVOPs) is presented. This algorithm can be seen as a variant of the multi-objective s…
Cheating is evolutionarily assimilated with cooperation in the continuous snowdrift game
Tatsuya Sasaki, Isamu Okada
It is well known that in contrast to the Prisoner's Dilemma, the snowdrift game can lead to a stable coexistence of cooperators and cheaters. Recent theoretical evidence on the sno…
Bayesian cluster analysis: Point estimation and credible balls
Sara Wade, Zoubin Ghahramani
Clustering is widely studied in statistics and machine learning, with applications in a variety of fields. As opposed to classical algorithms which return a single clustering solut…
Identifying Mixtures of Mixtures Using Bayesian Estimation
Gertraud Malsiner-Walli, Sylvia Frühwirth-Schnatter, Bettina Grün
The use of a finite mixture of normal distributions in model-based clustering allows to capture non-Gaussian data clusters. However, identifying the clusters from the normal compon…
