• Evaluating causes of algorithmic bias in juvenile criminal recidivism

  Miron, Marius; Tolan, Songül; Gómez Gutiérrez, Emilia, 1975-; Castillo, Carlos (Springer, 2020)

  In this paper we investigate risk prediction of criminal re-offense among juvenile defendants using general-purpose machine learning (ML) algorithms. We show that in our dataset, containing hundreds of cases, ML models ...
• From cognitive control to visual incongruity: conflict detection in surrealistic images

  Ruzzoli, Manuela; McGuinness, Aoife; Morís Fernández, Luis, 1982-; Soto-Faraco, Salvador, 1970- (Public Library of Science (PLoS), 2020)

  This study explored brain responses to images that exploit incongruity as a creative technique, often used in advertising (i.e., surrealistic images). We hypothesized that these images would reveal responses akin to cognitive ...
• 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)

  Current evidence suggests that volitional opening or closing of the eyes modulates brain activity and connectivity. However, how the eye state influences the functional connectivity of the primary visual cortex has been ...
• Cortical-inspired Wilson–Cowan-type equations for orientation-dependent contrast perception modelling

  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)

• 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 ...
