Publikováno v: CHAOS: An Interdisciplinary Journal of Nonlinear Science; in print, October 2024

An efficient method of exploring the effects of anisotropy in the fractal properties of 2D surfaces and images is proposed. It can be viewed as a direction-sensitive generalization of the multifractal detrended fluctuation analysis (MFDFA) into 2D. I

Improving Noise Robustness through Abstractions and its Impact on Machine Learning

Autor: Ibias, Alfredo, Capala, Karol, Varma, Varun Ravi, Drozdz, Anna, Sousa, Jose

Noise is a fundamental problem in learning theory with huge effects in the application of Machine Learning (ML) methods, due to real world data tendency to be noisy. Additionally, introduction of malicious noise can make ML methods fail critically, a

As evidenced by recent survey results, majority of asteroids are slow rotators (P>12 h), but lack spin and shape models due to selection bias. This bias is skewing our overall understanding of the spins, shapes, and sizes of asteroids, as well as of
