Aligning Recommendations with User Popularity Preferences
Mona Schirmer, Anton Thielmann, Pola Schwöbel +4
Popularity bias is a pervasive problem in recommender systems, where recommendations disproportionately favor popular items. This not only results in "rich-get-richer" dynamics and…
The Role of Graph Topology in the Performance of Biomedical Knowledge Graph Completion Models
Alberto Cattaneo, Stephen Bonner, Thomas Martynec +4
Knowledge Graph Completion has been increasingly adopted as a useful method for helping address several tasks in biomedical research, such as drug repurposing or drug-target identi…
Long-range Order and Directional Defect Propagation in the Nonreciprocal XY Model with Vision Cone Interactions
Sarah A. M. Loos, Sabine H. L. Klapp, Thomas Martynec
We study a two-dimensional, nonreciprocal XY model, where each spin interacts only with its nearest neighbours in a certain angle around its current orientation, i.e., its `vision…
Entropy production at criticality in a nonequilibrium Potts model
Thomas Martynec, Sabine H. L. Klapp, Sarah A. M. Loos
Understanding nonequilibrium systems and the consequences of irreversibility for the system's behavior as compared to the equilibrium case, is a fundamental question in statistical…
Modeling of nonequilibrium surface growth by a limited mobility model with distributed diffusion length
Thomas Martynec, Sabine H. L. Klapp
Kinetic Monte-Carlo (KMC) simulations are a well-established numerical tool to investigate the time-dependent surface morphology in molecular beam epitaxy (MBE) experiments. In par…
Impact of anisotropic interactions on non-equilibrium cluster growth at surfaces
Thomas Martynec, Sabine H. L. Klapp
Using event-driven kinetic Monte-Carlo simulations we investigate the early stage of non-equilibrium surface growth in a generic model with anisotropic interactions among the adsor…
One-particle density matrix characterization of many-body localization
Soumya Bera, Thomas Martynec, Henning Schomerus +2
We study a model of interacting fermions in one dimension subject to random, uncorrelated onsite disorder. The model realizes an interaction-driven quantum phase transition between…
