Deep Quantile and Deep Composite Model Regression
Tobias Fissler, Michael Merz, Mario V. Wüthrich
A main difficulty in actuarial claim size modeling is that there is no simple off-the-shelf distribution that simultaneously provides a good distributional model for the main body…
On unbounded polyhedral convex set optimization problems
Niklas Hey, Andreas Löhne
A polyhedral convex set optimization problem is given by a set-valued objective mapping from the -dimensional to the -dimensional Euclidean space whose graph is a convex poly…
Is the mode elicitable relative to unimodal distributions?
Claudio Heinrich-Mertsching, Tobias Fissler
Statistical functionals are called elicitable if there exists a loss or scoring function under which the functional is the optimal point forecast in expectation. While the mean and…
Characterizing and Computing the Set of Nash Equilibria via Vector Optimization
Zachary Feinstein, Birgit Rudloff
Nash equilibria and Pareto optimality are two distinct concepts when dealing with multiple criteria. It is well known that the two concepts do not coincide. However, in this work w…
BROUTE: a benchmark suite for the implementation of standard vehicle routing algorithms
Fabien Tricoire
We introduce BROUTE, a benchmark suite for vehicle routing optimization algorithms. We define a selection of algorithms traditionally used in vehicle routing optimization. They cap…
The Geography of Open Source Software: Evidence from GitHub
Johannes Wachs, Mariusz Nitecki, William Schueller +1
Open Source Software (OSS) plays an important role in the digital economy. Yet although software production is amenable to remote collaboration and its outputs are easily shared ac…
Markov-Modulated Affine Processes
Kevin Kurt, Rüdiger Frey
We study Markov-modulated affine processes (abbreviated MMAPs), a class of Markov processes that are created from affine processes by allowing some of their coefficients to be a fu…
The Connection between Process Complexity of Event Sequences and Models discovered by Process Mining
Adriano Augusto, Jan Mendling, Maxim Vidgof +1
Process mining is a research area focusing on the design of algorithms that can automatically provide insights into business processes. Among the most popular algorithms are those…
Process Model Forecasting Using Time Series Analysis of Event Sequence Data
Johannes De Smedt, Anton Yeshchenko, Artem Polyvyanyy +2
Process analytics is an umbrella of data-driven techniques which includes making predictions for individual process instances or overall process models. At the instance level, vari…
Backtesting Systemic Risk Forecasts using Multi-Objective Elicitability
Tobias Fissler, Yannick Hoga
Systemic risk measures such as CoVaR, CoES and MES are widely-used in finance, macroeconomics and by regulatory bodies. Despite their importance, we show that they fail to be elici…
Detection of statistically significant differences between process variants through declarative rules
Alessio Cecconi, Adriano Augusto, Claudio Di Ciccio
Services and products are often offered via the execution of processes that vary according to the context, requirements, or customisation needs. The analysis of such process varian…
Holdout-Based Fidelity and Privacy Assessment of Mixed-Type Synthetic Data
Michael Platzer, Thomas Reutterer
AI-based data synthesis has seen rapid progress over the last several years, and is increasingly recognized for its promise to enable privacy-respecting high-fidelity data sharing.…
Mining DEV for social and technical insights about software development
Maria Papoutsoglou, Johannes Wachs, Georgia M. Kapitsaki
Software developers are social creatures: they communicate, collaborate, and promote their work in a variety of channels. Twitter, GitHub, Stack Overflow, and other platforms offer…
SoK: Decentralized Exchanges (DEX) with Automated Market Maker (AMM) Protocols
Jiahua Xu, Krzysztof Paruch, Simon Cousaert +1
As an integral part of the decentralized finance (DeFi) ecosystem, decentralized exchanges (DEXs) with automated market maker (AMM) protocols have gained massive traction with the…
A LP relaxation based matheuristic for multi-objective integer programming
Duleabom An, Sophie N. Parragh, Markus Sinnl +1
Motivated by their success in the single-objective domain, we propose a very simple linear programming-based matheuristic for tri-objective binary integer programming. To tackle th…
Intelligent Software Web Agents: A Gap Analysis
Sabrina Kirrane
Semantic web technologies have shown their effectiveness, especially when it comes to knowledge representation, reasoning, and data integration. However, the original semantic web…
How many data clusters are in the Galaxy data set? Bayesian cluster analysis in action
Bettina Grün, Gertraud Malsiner-Walli, Sylvia Frühwirth-Schnatter
In model-based clustering, the Galaxy data set is often used as a benchmark data set to study the performance of different modeling approaches. Aitkin (2001) compares maximum likel…
Does Crowdfunding Really Foster Innovation? Evidence from the Board Game Industry
Johannes Wachs, Balazs Vedres
Crowdfunding offers inventors and entrepreneurs alternative access to resources with which they can develop and realize their ideas. Besides helping to secure capital, crowdfunding…
