• Opening or closing eyes at rest modulates the functional connectivity of V1 with default and salience networks

  Costumero, Víctor; Bueichekú, Elisenda; Adrián Ventura, Jesús; Ávila, César (Springer, 2020)

  Bertalmío, Marcelo; Calatroni, Luca; Franceschi, Valentina; Franceschiello, Benedetta; Prandi, Dario (Springer, 2020)

  We consider the evolution model proposed in Bertalmío (Front Comput Neurosci 8:71, 2014), Bertalmío et al. (IEEE Trans Image Process 16(4):1058–1072, 2007) to describe illusory contrast perception phenomena induced by ...
• Genetic algorithm with healthy population and multiple streams sharing information for clustering

  Beg, Abul Hashem; Islam, Md Zahidul; Estivill-Castro, Vladimir (Elsevier, 2016)

  Many popular clustering techniques including K-means require various user inputs such as the number of clusters k, which can often be very difficult for a user to guess in advance. Moreover, existing techniques like K-means ...
• Autonomous stock counting based on a stigmergic algorithm for multi-robot systems

  Casamayor-Pujol, Victor; Morenza-Cinos, Marc; Gastón, Bernat; Pous Andrés, Rafael (Elsevier, 2020)

  Maintaining an accurate and close to real time inventory of items is crucial for an efficient Supply Chain Management (SCM), which is one of the main pillars of successful business decisions in the retail market. Due to ...
• A synthetic data generator for online social network graphs

  Nettleton, David F. (Springer, 2016)

  Two of the difficulties for data analysts of online social networks are (1) the public availability of data and (2) respecting the privacy of the users. One possible solution to both of these problems is to use synthetically ...
• Combining K-MEANS and a genetic algorithm through a novel arrangement of genetic operators for high quality clustering

  Islam, Zahidul; Estivill Castro, Vladimir; Rahman, Anisur; Bossomaier, Terry (Elsevier, 2018)

  Knowledge discovery from data can be broadly categorized into two types: supervised and unsupervised. A supervised knowledge discovery process such as classification by decision trees typically requires class labels which ...
• Visual information flow in Wilson–Cowan networks

  Gómez Villa, Alexander; Bertalmío, Marcelo; Malo, Jesús (American Physiological Society, 2020)

  In this paper, we study the communication efficiency of a psychophysically tuned cascade of Wilson–Cowan and divisive normalization layers that simulate the retina-V1 pathway. This is the first analysis of Wilson–Cowan ...
• Lifespan associated global patterns of coherent neural communication

  Sahoo, Bikash; Pathak, Anagh; Deco, Gustavo; Banerjee, Arpan; Roy, Dipanjan (Elsevier, 2020)

  Healthy ageing is accompanied by changes to spontaneous electromagnetic oscillations. At the macroscopic scale, previous studies have quantified the basic features, e.g., power and frequencies in rhythms of interest from ...
• A neuronal theory of sequential economic choice

  Hayden, Benjamin Y.; Moreno Bote, Rubén (SAGE Publications, 2018)

  Results of recent studies point towards a new framework for the neural bases of economic choice. The principles of this framework include the idea that evaluation is limited to a single option within the focus of attention ...
• Integrating lexical and prosodic features for automatic paragraph segmentation

  Lai, Catherine; Farrús, Mireia; Moore, Johanna D. (Elsevier, 2020)

  Spoken documents, such as podcasts or lectures, are a growing presence in everyday life. Being able to automatically identify their discourse structure is an important step to understanding what a spoken document is about. ...
• Individual differences in hippocampal volume as a function of BMI and reward sensitivity

  Parcet, Maria-Antònia; Adrián Ventura, Jesús; Costumero, Víctor; Ávila, César (Frontiers, 2020)
