Factorizable joint shift revisited

Dirk Tasche

Factorizable joint shift (FJS) represents a type of distribution shift (or dataset shift) that comprises both covariate and label shift. Recently, it has been observed that FJS act…

Stellar Forcing of (exo)Planetary Environments

Julián D. Alvarado-Gómez, Erika Palmerio, Manuel Güdel +13

The environments of exoplanets are fundamentally shaped by the magnetic activity of their host stars through radiative, plasma, and particle-driven processes. This article presents…

Kerr black hole in presence of force-free magnetic field

Haidar Sheikhahmadi

We extend the study of force-free magnetospheres from non-rotating to rotating black holes \cite{Sheikhahmadi} and investigate the influence of a force-free magnetic field on the g…

Data Pruning: Redundant, Problematic, and Interdependent Samples

Leon Freese, Marthinus W. Theunissen

The performance of deep learning models is affected by not only data quantity but also data quality. Data pruning is a process by which practitioners can reduce the size of a datas…

Covariant Tolman-Oppenheimer-Volkoff equations in Energy-Momentum Squared Gravity

Eduardo Bittencourt, Mariam Campbell, Peter K. S. Dunsby +2

We study static, spherically symmetric stellar configurations in an extended class of Energy--Momentum Squared Gravity using the covariant \(1+1+2\) semi-tetrad formalism. For perf…

Feature extraction for plant growth estimation

Simbarashe Aldrin Ngorima, Albert Helberg, Marelie H. Davel

Precision agriculture requires the estimation of plant growth stages in real-time. When the plant growth stage is known, the wastage of resources in cultivation, such as nutrients…
