A large-scale empirical investigation of specialization in criminal career

open access: yesScientific Reports, 2023
We use a comprehensive longitudinal dataset on criminal acts over 6 years in a European country to study specialization in criminal careers. We present a method to cluster crime categories by their relative co-occurrence within criminal careers, deriving

Inequality and inequity in network-based ranking and recommendation algorithms

open access: yesScientific Reports, 2022
Though algorithms promise many benefits including efficiency, objectivity and accuracy, they may also introduce or amplify biases. Here we study two well-known algorithms, namely PageRank and Who-to-Follow (WTF), and show to what extent their ranks ...

Quantifying firm-level economic systemic risk from nation-wide supply networks

open access: yesScientific Reports, 2022
Crises like COVID-19 exposed the fragility of highly interdependent corporate supply networks and the complex production processes depending on them. However, a quantitative assessment of individual companies’ impact on the networks’ overall production ...

Stress-testing the resilience of the Austrian healthcare system using agent-based simulation

open access: yesNature Communications, 2022
As mass quarantines, absences due to sickness, or other shocks thin out patient-physician networks, the system might be pushed to a tipping point where it loses its ability to deliver care.

The individual dynamics of affective expression on social media

open access: yesEPJ Data Science, 2020
Understanding the temporal dynamics of affect is crucial for our understanding human emotions in general. In this study, we empirically test a computational model of affective dynamics by analyzing a large-scale dataset of Facebook status updates using ...

From average case complexity to improper learning complexity [PDF]

open access: yes, 2014
The basic problem in the PAC model of computational learning theory is to determine which hypothesis classes are efficiently learnable. There is presently a dearth of results showing hardness of learning problems. Moreover, the existing lower bounds fall

Cosmological Complexity

open access: yes, 2020
We compute the quantum circuit complexity of the evolution of scalar curvature perturbations on expanding backgrounds, using the language of squeezed vacuum states.
