    Synthetic terrains play a vital role in various applications, including entertainment, training, and simulation. This work focuses on rocky terrains akin to those found in alpine environments, which contain many complex ...
  • Hyppo: using equivalences to optimize pipelines in exploratory machine learning 

    Kontaxakis, Antonios; Sacharidis, Dimitris; Simitsis, Alkis; Abelló Gamazo, Alberto; Nadal Francesch, Sergi (Institute of Electrical and Electronics Engineers (IEEE), 2024)
    Conference report
    Open Access
    We present HYPPO, a novel system to optimize pipelines encountered in exploratory machine learning. HYPPO exploits alternative computational paths of artifacts from past executions to derive better execution plans while ...
  • Accelerating long sequence alignment using processing-in-memory 

    Alonso Marín, Alejandro; Fernández Vega, Ivan; Marco Sola, Santiago; Gómez Luna, Juan; Aguado Puig, Quim; Moretó Planas, Miquel (2024-06-18)
    Research report
    Open Access
    Recent advances in sequencing technologies have made sequence analysis algorithms a fundamental tool for genomics and healthcare research. In particular, sequence alignment is a fundamental building block present in numerous ...
  • Effects of colour and scene dynamism on visual fatigue in animated films 

    Argilés Sans, Marc; Fonts González, Elisabet; Pérez Maña, Luis; Martínez Navarro, Beatriz; Sora Domenjó, Carles; Pérez Cabré, Elisabet; Sunyer Grau, Bernat; Rovira Gay, Cristina; Molins Pitarch, Carla; Quevedo Junyent, Luisa Jesús (Springer, 2024-11-04)
    Article
    Open Access
    Animated films are highly popular in society, particularly among children and adolescents. During film production, selecting an adequate colour palette and scene dynamism is crucial for creating a visual impact on the ...
  • Virtual reality inspection of chromatin 3D and 2D data 

    Molina López, Elena; Kouril, David; Isenberg, Tobias; Kozliková, Barbora; Vázquez Alcocer, Pere Pau (Elsevier, 2024-11)
    Article
    Open Access
    Understanding the packing of long DNA strands into chromatin is one of the ultimate challenges in genomic research. An intrinsic part of this complex problem is studying the chromatin’s spatial structure. Biologists ...
  • Mitigating data sparsity in integrated data through text conceptualization 

    Rahman, Md Ataur; Nadal Francesch, Sergi; Romero Moral, Óscar; Sacharidis, Dimitris (Institute of Electrical and Electronics Engineers (IEEE), 2024)
    Conference report
    Open Access
    We study the data sparsity problem for data generated from an integration system. We approach the problem from a textual information extraction perspective and propose to conceptualize external documents using the concepts ...
  • Stretch your reach: studying self-avatar and controller misalignment in virtual reality interaction 

    Pontón Martínez, José Luis; Keshavarz, Reza; Beacco Porres, Alejandro; Pelechano Gómez, Núria (Association for Computing Machinery (ACM), 2024)
    Conference report
    Open Access
    Immersive Virtual Reality typically requires a head-mounted display (HMD) to visualize the environment and hand-held controllers to interact with the virtual objects. Recently, many applications display full-body avatars ...
  • Finding relevant information in big datasets with ML 

    Njoku, Uchechukwu Fortune; Abelló Gamazo, Alberto; Bilalli, Besim; Bontempi, Gianluca (OpenProceedings, 2024)
    Conference lecture
    Open Access
    Due to the abundance of data, noisy, irrelevant, or redundant features often need to be identified and discarded. Feature selection is a collection of methods used to ensure that only relevant data are used for a data ...
  • Rendering piecewise approximations of SDFs through analytic intersections 

    Pujol Puig, Eduard; Chica Calaf, Antonio (Elsevier, 2024-08)
    Article
    Open Access
    Signed distance fields (SDFs) have emerged as an alternative shape representation for real-time collision detection and lighting effects. Computing these for complex models can be expensive, so one popular approach is to ...
  • Effect of color palettes in heatmaps perception: a study 

    Molina López, Elena; Middel Soria, Carolina; Vázquez Alcocer, Pere Pau (European Association for Computer Graphics (Eurographics), 2023)
    Conference lecture
    Open Access
    Heatmaps are a widely used technique in visualization. Unfortunately, they have not been investigated in depth and little is known about the best parameterizations so that they are properly interpreted. The effect of ...
  • Exploring the role of expected collision feedback in crowded virtual environments 

    Yun, Haoran; Pontón Martínez, José Luis; Beacco Porres, Alejandro; Andújar Gran, Carlos Antonio; Pelechano Gómez, Núria (Institute of Electrical and Electronics Engineers (IEEE), 2024)
    Conference report
    Open Access
    An increasing number of virtual reality applications require environments that emulate real-world conditions. These environments often involve dynamic virtual humans showing realistic behaviors. Understanding user perception ...
  • A data-science pipeline to enable the interpretability of many-objective feature selection 

    Njoku, Uchechukwu Fortune; Abelló Gamazo, Alberto; Bilalli, Besim; Bontempi, Gianluca (CEUR-WS.org, 2024)
    Conference lecture
    Open Access
    Many-Objective Feature Selection (MOFS) approaches use four or more objectives to determine the relevance of a subset of features in a supervised learning task. As a consequence, MOFS typically returns a large set of ...
