    Ugrinovic Kehdy, Nicolas; Pumarola Peris, Albert; Sanfeliu Cortés, Alberto; Moreno-Noguer, Francesc (Scitepress, 2022)
    Conference report
    Open Access
    Recent advances in 3D human shape reconstruction from single images have shown impressive results, leveraging on deep networks that model the so-called implicit function to learn the occupancy status of arbitrarily dense ...
  • Molecular dynamics forecasting of transmembrane regions in GPRCs by recurrent neural networks 

    López Correa, Juan Manuel; König, Caroline; Vellido Alcacena, Alfredo (Institute of Electrical and Electronics Engineers (IEEE), 2022)
    Conference report
    Open Access
    G protein-coupled receptors are a large super-family of cell membrane proteins that play an important physiological role as transmitters of extra-cellular signals. Signal transmission through the cell membrane depends on ...
  • A deep learning-based method for uncovering GPCR ligand-induced conformational states using interpretability techniques 

    Gutiérrez Mondragón, Mario Alberto; König, Caroline; Vellido Alcacena, Alfredo (Springer, 2022)
    Conference report
    Restricted access - publisher's policy
    There is increasing interest in the development of tools for investigating the protein ligand space. Understanding the underlying mechanisms of G protein-coupled receptors (GPCR) in the ligand-binding process is of particular ...
  • Measuring alignment bias in neural Seq2Seq semantic parsers 

    Locatelli, Davide; Quattoni, Ariadna Julieta (Association for Computational Linguistics, 2022)
    Conference report
    Open Access
    Prior to deep learning the semantic parsing community has been interested in understanding and modeling the range of possible word alignments between natural language sentences and their corresponding meaning representations. ...
  • Testing reinforcement learning explainability methods in a multi-agent cooperative environment 

    Domènech Vila, Marc; Gnatyshak, Dmitry; Tormos Llorente, Adrián; Álvarez Napagao, Sergio (IOS Press, 2022)
    Conference report
    Open Access
    The adoption of algorithms based on Artificial Intelligence (AI) has been rapidly increasing during the last years. However, some aspects of AI techniques are under heavy scrutiny. For instance, in many cases, it is not ...
  • Focus and bias: will it blend? 

    Arias Duart, Anna; Parés Pont, Ferran; Giménez Ábalos, Víctor; Garcia Gasulla, Dario (IOS Press, 2022)
    Conference report
    Open Access
    One direct application of explainable AI feature attribution methods is to be used for detecting unwanted biases. To do so, domain experts typically have to review explained inputs, checking for the presence of unwanted ...
  • Bootstrap-CURE clustering: An investigation of impact of shrinking on clustering performance 

    Karna, Ashutosh; Gibert, Karina (IOS Press, 2022)
    Conference report
    Open Access
    Hierarchical clustering is one of the most popular techniques in unsupervised segmentation. However, since it has quadratic complexity as it is based on pairwise distance matrix construction, it tends to be less used with ...
  • Optimizing online time-series data imputation through case-based reasoning 

    Pascual Pañach, Josep; Sànchez-Marrè, Miquel; Cugueró Escofet, Miquel Àngel (IOS Press, 2022)
    Conference report
    Open Access
    When working with Intelligent Decision Support Systems (IDSS), data quality could compromise decisions and therefore, an undesirable behaviour of the supported system. In this paper, a novel methodology for time-series ...
  • Long short-term memory to predict 3D amino acids positions in GPCR molecular dynamics 

    López Correa, Juan Manuel; König, Caroline; Vellido Alcacena, Alfredo (IOS Press, 2022)
    Conference report
    Open Access
    G-Protein Coupled Receptors (GPCRs) are a big family of eukaryotic cell transmembrane proteins, responsible for numerous biological processes. From a practical viewpoint around 34% of the drugs approved by the US Food and ...
  • Human-in-the-loop online multi-agent approach to increase trustworthiness in ML models through trust scores and data augmentation
