  • A resilient and distributed near real-time traffic forecasting application for Fog computing environments 

    Pérez, Juan L.; Gutierrez-Torre, Alberto; Berral, Josep Ll.; Carrera, David (Elsevier, 2018-10)
    Article
    Open Access
    In this paper we propose an architecture for a city-wide traffic modeling and prediction service based on the Fog Computing paradigm. The work assumes an scenario in which a number of distributed antennas receive data ...
  • Automatic Generation of Workload Profiles Using Unsupervised Learning Pipelines 

    Buchaca Prats, David; Berral, Josep Ll.; Carrera, David (IEEE, 2018-03)
    Article
    Open Access
    The complexity of resource usage and power consumption on cloud-based applications makes the understanding of application behavior through expert examination difficult. The difficulty increases when applications are seen ...
  • Constant-Time Sliding Window Framework with Reduced Memory Footprint and Efficient Bulk Evictions 

    Villalba, Álvaro; Berral, Josep Ll.; Carrera, David (IEEE, 2019-03-01)
    Article
    Open Access
    The fast evolution of data analytics platforms has resulted in an increasing demand for real-time data stream processing. From Internet of Things applications to the monitoring of telemetry generated in large data centers, ...
  • Database integrated analytics using R : initial experiences with SQL-Server + R 

    Berral, Josep Ll.; Poggi, Nicolas (2016)
    Conference lecture
    Open Access
    Most data scientists use nowadays functional or semi-functional languages like SQL, Scala or R to treat data, obtained directly from databases. Such process requires to fetch data, process it, then store again, and such ...
  • Modeling cloud resources using machine learning 

    Berral, Josep Ll.; Gavaldà Mestre, Ricard; Torres Viñals, Jordi (2013)
    External research report
    Open Access
    Cloud computing is a new Internet infrastructure paradigm where management optimization has become a challenge to be solved, as all current management systems are human-driven or ad-hoc automatic systems that must be tuned ...
