Guarding Offices with Maximum Dispersion
We investigate the Dispersive Art Gallery Problem with vertex guards and rectangular visibility ($r$-visibility) for a class of orthogonal polygons that reflect the properties of real-world floor plans: these office-like polygons consist of rectangular rooms and corridors. In the dispersive variant of the Art Gallery Problem, the objective is not to minimize the number of guards but to maximize the minimum geodesic $L_1$-distance between any two guards, called the dispersion distance. Our mai…

Linken-Chef van Aken gegen NATO-Soldaten in der Ukraine
Der Co-Vorsitzende der Linken, Jan van Aken, ist dagegen, dass NATO-Soldaten einen möglichen Frieden in der Ukraine absichern. Dadurch entstehe die "ganz große Gefahr", dass sich nach einem Waffenstillstand NATO- und russische Soldaten direkt gegenüberstünden. Stattdessen sei eine Mission der Vereinten Nationen besser, sagte er im gemeinsamen Morgenmagazin von ARD und ZD…

DocPolarBERT: A Pre-trained Model for Document Understanding with Relative Polar Coordinate Encoding of Layout Structures
We introduce DocPolarBERT, a layout-aware BERT model for document understanding that eliminates the need for absolute 2D positional embeddings. We extend self-attention to take into account text block positions in relative polar coordinate system rather than the Cartesian one. Despite being pre-trained on a dataset more than six times smaller than the widely used IIT-CDIP corpus, DocPolarBERT achieves state-of-the-art results. These results demonstrate that a carefully designed attention mechan…

A Better Multi-Objective GP-GOMEA -- But do we Need it?
In Symbolic Regression (SR), achieving a proper balance between accuracy and interpretability remains a key challenge. The Genetic Programming variant of the Gene-pool Optimal Mixing Evolutionary Algorithm (GP-GOMEA) is of particular interest as it achieves state-of-the-art performance using a template that limits the size of expressions. A recently introduced expansion, modular GP-GOMEA, is capable of decomposing expressions using multiple subexpressions, further increasing chances of interpre…
