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-García, 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…
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…
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,…
An Evaluation of Hybrid Annotation Workflows on High-Ambiguity Spatiotemporal Video Footage
Juan Gutiérrez, Victor Gutiérrez, Ángel 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…
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…
Open-Source System for Multilingual Translation and Cloned Speech Synthesis
Mateo Cámara, Juan Gutiérrez, María Pilar Daza +1
We present an open-source system designed for multilingual translation and speech regeneration, addressing challenges in communication and accessibility across diverse linguistic c…
The Dark Ages Explorer (DEX): a filled-aperture ultra-long wavelength radio interferometer on the lunar far side
C. D. Brinkerink, M. J. Arts, M. J. Bentum +21
The measurement of the spatial fluctuations of the neutral hydrogen 21 cm signal arising during the Dark Ages and Cosmic Dawn periods of our Universe (z from 200 to 10) holds the p…
Towards a Dual Version of Woodall's Conjecture for Partial 3-Trees
Juan Gutiérrez
A dual version of a conjecture by Woodall asserts that, in a planar digraph, the length of a shortest dicycle equals the maximum number of pairwise disjoint feedback arc sets. We v…
Domination and packing in graphs
Renzo Gómez, Juan Gutiérrez
Given a graph~, the domination number, denoted by~, is the minimum cardinality of a dominating set in~. Dual to the notion of domination number is the packing number of…
On two conjectures about the intersection of longest paths and cycles
Juan Gutiérrez, Christian Valqui
A conjecture attributed to Smith states that every pair of longest cycles in a -connected graph intersect each other in at least vertices. In this paper, we show that every…
Risk bounds for aggregated shallow neural networks using Gaussian prior
Laura Tinsi, Arnak S. Dalalyan
Analysing statistical properties of neural networks is a central topic in statistics and machine learning. However, most results in the literature focus on the properties of the ne…
