Multifractal Signatures of Ageing and Dementia Development: A Multifractal Space-Filling Curve Analysis
Marta Lotka, Jacek Grela, Zbigniew Drogosz +2
Multifractality is an effective formalism for quantifying the nonlinear, scale-free properties of complex data. In this study, we propose a novel and efficient methodology, termed…
StylOch at PAN: Gradient-Boosted Trees with Frequency-Based Stylometric Features
Jeremi K. Ochab, Mateusz Matias, Tymoteusz Boba +1
This submission to the binary AI detection task is based on a modular stylometric pipeline, where: public spaCy models are used for text preprocessing (including tokenisation, name…
Stylometry recognizes human and LLM-generated texts in short samples
Karol Przystalski, Jan K. Argasiński, Iwona Grabska-Gradzińska +1
The paper explores stylometry as a method to distinguish between texts created by Large Language Models (LLMs) and humans, addressing issues of model attribution, intellectual prop…
Investigating structural and functional aspects of the brain's criticality in stroke
Jakub Janarek, Zbigniew Drogosz, Jacek Grela +2
This paper addresses the question of the brain's critical dynamics after an injury such as a stroke. It is hypothesized that the healthy brain operates near a phase transition (cri…
Task-dependent fractal patterns of information processing in working memory
Jeremi K. Ochab, Marcin Wątorek, Anna Ceglarek +5
We applied detrended fluctuation analysis, power spectral density, and eigenanalysis of detrended cross-correlations to investigate fMRI data representing a diurnal variation of wo…
Untangling the brain web: from the early days of complex functional networks to the non-linear dynamical directed functional connectivity measures
Dante R. Chialvo, Ignacio Cifre, Jeremi K. Ochab
Already two decades passed since the first applications of graph theory to brain neuroimaging. Since that early description, the characterization of the brain as a very large inter…
