Consensus group decision making under model uncertainty with a view towards environmental policy making
Phoebe Koundouri, Georgios I. Papayiannis, Electra V. Petracou +1
In this paper we propose a consensus group decision making scheme under model uncertainty consisting of an iterative two-stage procedure and based on the concept of Fréchet barycen…
A Framework for Treating Model Uncertainty in the Asset Liability Management Problem
Georgios I. Papayiannis
The problem of asset liability management (ALM) is a classic problem of the financial mathematics and of great interest for the banking institutions and insurance companies. Severa…
Robust Policy Selection and Harvest Risk Quantification for Natural Resources Management under Model Uncertainty
Georgios I. Papayiannis
In this work the problem of optimal harvesting policy selection for natural resources management under model uncertainty is investigated. Under the framework of the neoclassical gr…
Modelling of functional profiles and explainable shape shifts detection: An approach combining the notion of the Fréchet mean with the shape invariant model
Georgios I. Papayiannis, Stelios Psarakis, Athanasios N. Yannacopoulos
A modelling framework suitable for detecting shape shifts in functional profiles combining the notion of Fréchet mean and the concept of deformation models is developed and propose…
On non-monochromatic plane-wave solutions of Maxwell's equations
C. J. Papachristou
In electrodynamics courses and textbooks the properties of plane electromagnetic waves in both conducting and non-conducting media are typically studied from the point of view of t…
On clustering uncertain and structured data with Wasserstein barycenters and a geodesic criterion for the number of clusters
G. I. Papayiannis, G. N. Domazakis, D. Drivaliaris +3
In this work clustering schemes for uncertain and structured data are considered relying on the notion of Wasserstein barycenters, accompanied by appropriate clustering indices bas…
