'Adaptive Seriational Risk Parity' and other Extensions for Heuristic Portfolio Construction using Machine Learning and Graph Theory

Jaeger, Markus; Krügel, Stephan; Papenbrock, Jochen; … - 2021

In this article, the authors present a conceptual framework named 'Adaptive Seriational Risk Parity' (ASRP) to extend Hierarchical Risk Parity (HRP) as an asset allocation heuristic. The first step of HRP (quasi-diagonalization) determining the hierarchy of assets is required for the actual...

Text to process model : automating process model creation from text

Nolte, Felix Reinold - 2021

The description and visualization of processes and underlying requirements are a core task in IT projects today. The translation of information between different forms of representation is used to include these efficiently in the different steps of a project, e.g., to describe the as-is and...

Random Directed Graph Distributions in the Triad Census in Social Networks

Wasserman, Stanley S. - 2021

This paper uses the concept of the triad census first introduced by Holland and Leinhardt, and describes several distributions on directed graphs. Methods are presented for calculating the mean and the covariance matrix of the triad census for the uniform distribution that conditions on the...

Stable Cores in Information Graph Games

Núñez, Marina; Vidal-Puga, Juan J. - 2021

In an information graph situation, some agents that are connected by an undirected graph can share with no cost some information or technology that can also be obtained from a source. If an agent is not connected to an informed player, this agent pays a unitary cost to obtain this technology. A...
