  • Synthetic dataset generation with itemset-based generative models 

    Lezcano Ríos, Christian Gerardo; Arias Vicente, Marta (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference report
    Open Access
    This paper proposes three different data generators, tailored to transactional datasets, based on existing itemset-based generative models. All these generators are intuitive and easy to implement and show satisfactory ...
  • Characterizing transactional databases for frequent itemset mining 

    Lezcano Ríos, Christian Gerardo; Arias Vicente, Marta (CEUR-WS.org, 2019)
    Conference report
    Open Access
    This paper presents a study of the characteristics of transactional databases used in frequent itemset mining. Such characterizations have typically been used to benchmark and understand the data mining algorithms working ...
  • Effective visualization of sparse image-to-image correspondences 

    Andújar Gran, Carlos Antonio; Chica Calaf, Antonio; Comino Trinidad, Marc (European Association for Computer Graphics (Eurographics), 2020)
    Conference report
    Open Access
    Finding robust correspondences between images is a crucial step in photogrammetry applications. The traditional approach to visualize sparse matches between two images is to place them side-by-side and draw link segments ...
  • A Tool for N-way analysis of programming exercises 

    Andújar Gran, Carlos Antonio; Comino Trinidad, Marc; Fairén González, Marta; Vinacua Pla, Álvaro (European Association for Computer Graphics (Eurographics), 2020)
    Conference report
    Open Access
    Programming exercises are a corner stone in Computer Science courses. If used properly, these exercises provide valuable feedback both to students and instructors. Unfortunately, the assessment of student submissions through ...
  • A semantic model to fight social exclusion 

    Ortiz Santiago, Víctor Alejandro; Estañol Lamarca, Montserrat; Marinescu, Maria Cristina; Sancho Samsó, María Ribera; Teniente López, Ernest; Rueda Palenzuela, Carmen (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference lecture
    Open Access
    This work presents a semantic model meant to help with the identification and prediction of individuals at risk of social exclusion. The model is based on the self-sufficiency matrix, a tool that evaluates a person's ...
  • Multi-view image fusion 

    Comino Trinidad, Marc; Martin Brualla, Ricardo; Kainz, Florian; Kontkanen, Janne (2019)
    Conference report
    Open Access
    We present an end-to-end learned system for fusing multiple misaligned photographs of the same scene into a chosen target view. We demonstrate three use cases: 1) color transfer for inferring color for a monochrome view, ...
  • A software service supporting software quality forecasting 

    Manzano Aguilar, Martí; Ayala Martínez, Claudia Patricia; Gómez Seoane, Cristina; López Cuesta, Lidia (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference report
    Open Access
    Software repositories such as source control, defect tracking systems and project management tools, are used to support the progress of software projects. The exploitation of such data with techniques like forecasting is ...
  • From process models to chatbots 

    López Cuenca, Francisco Anselmo; Sánchez Ferreres, Josep; Carmona Vargas, Josep; Padró, Lluís (Springer, 2019)
    Conference report
    Open Access
    The effect of digital transformation in organizations needs to go beyond automation, so that human capabilities are also augmented. A possibility in this direction is to make formal representations of processes more ...
  • Structural computation of alignments of business processes over partial orders 

    Taymouri, Farbod; Carmona Vargas, Josep (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference report
    Open Access
    Relating event data and process models is becoming an important element for organizations. This paper presents a novel approach for aligning traces and process models. The approach is based on the structural theory of Petri ...
  • Formal reasoning on natural language descriptions of processes 

    Sánchez Ferreres, Josep; Burattin, Andrea; Carmona Vargas, Josep; Montali, Marco; Padró, Lluís (Springer, 2019)
    Conference report
    Open Access
    The existence of unstructured information that describes processes represents a challenge in organizations, mainly because this data cannot be directly referred into process-aware ecosystems due to ambiguities. Still, this ...
  • Classification of changes in API evolution 

    Koçi, Rediana; Franch Gutiérrez, Javier; Jovanovic, Petar; Abelló Gamazo, Alberto (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference lecture
    Open Access
    Applications typically communicate with each other, accessing and exposing data and features by using Application Programming Interfaces (APIs). Even though API consumers expect APIs to be steady and well established, APIs ...
  • View-dependent hierarchical rendering of massive point clouds through textured splats 

    Comino Trinidad, Marc; Chica Calaf, Antonio; Andújar Gran, Carlos Antonio (European Association for Computer Graphics (Eurographics), 2019)
    Conference report
    Open Access
    Nowadays, there are multiple available range scanning technologies which can capture extremely detailed models of realworld surfaces. The result of such process is usually a set of point clouds which can contain billions ...
