Ordered Weighted Average Support Vector Regression
Luisa I. Martínez-Merino, Justo Puerto, Antonio M. Rodríguez-Chía
This paper introduces a novel Support Vector Regression (SVR) model that incorporates Ordered Weighted Average (OWA) operators to differently penalize deviations of observations fr…
A ready-to-deploy MLOps software platform for satellite and NEO detection at meter-class ground-based observatories
Rafael Carrillo Navarro, Pablo García-Martín, René Duffard +2
Ground-based astronomical observations frequently contain streaks produced by artificial satellites, space debris, and potentially Near-Earth Objects (NEOs). While machine-learning…
Late-time evolution of the interacting stripped-envelope supernova 2017dio
C. Humina, C. P. Gutiérrez, H. Kuncarayakti +14
The discovery of stripped-envelope supernovae (SNe) interacting with dense circumstellar medium (CSM) challenges our current understanding of massive star evolution. We present lat…
StreakMind: AI detection and analysis of satellite streaks in astronomical images with automated database integration
Rafael Carrillo Navarro, René Duffard, Pablo García-Martín +3
Artificial satellites and space debris increasingly contaminate astronomical images, affecting scientific surveys and producing large volumes of streaked exposures. Manual inspecti…
Hub location problems with asymmetric allocation
I. Espejo, M. Landete, M. Leal +1
Hub location problems are central to optimizing logistics, telecommunications, and transportation networks by consolidating flows through strategically placed hubs. While existing…
The Schwarz function and the shrinking of the Szegő curve: electrostatic, hydrodynamic, and random matrix models
Gabriel Álvarez, Luis Martínez Alonso, Elena Medina
We study the deformation of the classical Szegő curve given by , from three different viewpoints: an e…
