Separating Matchings in Cubic Graphs
Juan Gutiérrez, Renzo Gómez
We study separating matchings in graphs, that is, matchings whose removal increases the number of connected components, and focus on determining the maximum size of such a matching…
PANC: Prior-Aware Normalized Cut via Anchor-Augmented Token Graphs
Juan Gutiérrez, Victor Gutiérrez-GarcÃa, José Luis Blanco-Murillo
Unsupervised segmentation from self-supervised ViT patches holds promise but lacks robustness: multi-object scenes confound saliency cues, and low-semantic images weaken patch rele…
An Evaluation of Hybrid Annotation Workflows on High-Ambiguity Spatiotemporal Video Footage
Juan Gutiérrez, Victor Gutiérrez, Ãngel Mora +2
Manual annotation remains the gold standard for high-quality, dense temporal video datasets, yet it is inherently time-consuming. Vision-language models can aid human annotators an…
The Minimum Subgraph Complementation Problem
Juan Gutiérrez, Sagartanu Pal
Subgraph complementation is an operation that toggles all adjacencies inside a selected vertex set. Given a graph \(G\) and a target class \(\mathcal{C}\), the Minimum Subgraph Com…
Strong-lensing rates of massive black hole binaries in LISA
Juan Gutiérrez, Macarena Lagos
Similarly to electromagnetic (EM) signals, gravitational lensing by intervening galaxies can also affect gravitational waves (GWs). In this paper, we estimate the strong-lensing ra…
Homological epimorphisms in functor categories and singularity categories
Juan Andrés Orozco Gutiérrez, Valente Santiago Vargas
Given a homological epimorphism between -categories, we show that if the ideal satisfies certain conditions…
