Individual and collective gains from cooperation and reciprocity in a dynamic-network Prisoner's Dilemma driven by extraversion, openness, and agreeableness
David Abián, Jorge Bernad, Sergio Ilarri +1
How do stable personality differences shape cooperation when social ties can form and dissolve? We model a repeated Prisoner's Dilemma on an endogenous network in which three conti…
Communication-aware planning for robot teams deployment
Yaroslav Marchukov, Luis Montano
In the present work we address the problem of deploying a team of robots in a scenario where some locations of interest must be reached. Thus, a planning for a deployment is requir…
A* Based Algorithm for Reduced Complexity ML Decoding of Tailbiting Codes
Jorge Ortin, Paloma Garcia, Fernando Gutierrez +1
The A* algorithm is a graph search algorithm which has shown good results in terms of computational complexity for Maximum Likelihood (ML) decoding of tailbiting convolutional code…
Peripheral brain interfacing: Reading high-frequency brain signals from the output of the nervous system
Jaime Ibáñez, Blanka Zicher, Etienne Burdet +3
Accurate and robust recording and decoding from the central nervous system (CNS) is essential for advances in human-machine interfacing. However, technologies used to directly meas…
Explainable by-design Audio Segmentation through Non-Negative Matrix Factorization and Probing
Martin Lebourdais, Théo Mariotte, Antonio Almudévar +2
Audio segmentation is a key task for many speech technologies, most of which are based on neural networks, usually considered as black boxes, with high-level performances. However,…
OmniSCV: An Omnidirectional Synthetic Image Generator for Computer Vision
Bruno Berenguel-Baeta, Jesus Bermudez-Cameo, Jose J. Guerrero
Omnidirectional and 360° images are becoming widespread in industry and in consumer society, causing omnidirectional computer vision to gain attention. Their wide field of view all…
Floor extraction and door detection for visually impaired guidance
Bruno Berenguel-Baeta, Manuel Guerrero-Viu, Alejandro de Nova +3
Finding obstacle-free paths in unknown environments is a big navigation issue for visually impaired people and autonomous robots. Previous works focus on obstacle avoidance, howeve…
Cooperative Periodic Coverage With Collision Avoidance
José Manuel Palacios-Gasós, Eduardo Montijano, Carlos Sagüés +1
In this paper we propose a periodic solution to the problem of persistently covering a finite set of interest points with a group of autonomous mobile agents. These agents visit pe…
Intermittent Connectivity Maintenance With Heterogeneous Robots
Rosario Aragues, Dimos V. Dimarogonas, Pablo Guallar +1
We consider a scenario of cooperative task servicing, with a team of heterogeneous robots with different maximum speeds and communication radii, in charge of keeping the network in…
Scale-free vision-based aerial control of a ground formation with hybrid topology
Miguel Aranda, Youcef Mezouar, Gonzalo López-Nicolás +1
We present a novel vision-based control method to make a group of ground mobile robots achieve a specified formation shape with unspecified size. Our approach uses multiple aerial…
Modified Mach Zehnder interferometer for spatial coherence measurement
FJ Torcal-Milla, J Lobera, EM Roche +4
Spatial coherence of light sources is usually obtained by using the classical Youngs interferometer. Despite the original experiment has been improved in successive works, some dra…
Design and numerical analysis of metallic Ronchi diffraction gratings acting as reflective beam-splitter
Francisco Jose Torcal-Milla, Luis Miguel Sanchez-Brea
In this work, a reflective beam-splitter based on a metallic Ronchi diffraction grating normally illuminated is designed and analysed. This kind of beam-splitter could have potenti…
Event-Triggered Consensus for Continuous-Time Distributed Estimation
Irene Perez-Salesa, Rodrigo Aldana-Lopez, Carlos Sagues
Distributed sensor networks have gained interest thanks to the developments in processing power and communications. Event-triggering mechanisms can be useful in reducing communicat…
Multifractality in spin glasses
Janus Collaboration, M. Baity-Jesi, E. Calore +21
We unveil the multifractal behavior of Ising spin glasses in their low-temperature phase. Using the Janus II custom-built supercomputer, the spin-glass correlation function is stud…
ROBUSfT: Robust Real-Time Shape-from-Template, a C++ Library
Mohammadreza Shetab-Bushehri, Miguel Aranda, Youcef Mezouar +2
Tracking the 3D shape of a deforming object using only monocular 2D vision is a challenging problem. This is because one should (i) infer the 3D shape from a 2D image, which is a s…
Fast Autonomous Robotic Exploration Using the Underlying Graph Structure
Julio A. Placed, José A. Castellanos
In this work, we fully define the existing relationships between traditional optimality criteria and the connectivity of the underlying pose-graph in Active SLAM, characterizing, t…
EndoMapper dataset of complete calibrated endoscopy procedures
Pablo Azagra, Carlos Sostres, Ángel Ferrandez +15
Computer-assisted systems are becoming broadly used in medicine. In endoscopy, most research focuses on the automatic detection of polyps or other pathologies, but localization and…
Enough is Enough: Towards Autonomous Uncertainty-driven Stopping Criteria
Julio A. Placed, José A. Castellanos
Autonomous robotic exploration has long attracted the attention of the robotics community and is a topic of high relevance. Deploying such systems in the real world, however, is st…
Generalizing AUC Optimization to Multiclass Classification for Audio Segmentation With Limited Training Data
Pablo Gimeno, Victoria Mingote, Alfonso Ortega +2
Area under the ROC curve (AUC) optimisation techniques developed for neural networks have recently demonstrated their capabilities in different audio and speech related tasks. Howe…
