  • CGPA: Coarse-Grained Pruning of Activations for Energy-Efficient RNN Inference 

    Riera Villanueva, Marc; Arnau Montañés, José María; González Colás, Antonio María (2019-09-01)
    Article
    Open Access
    Recurrent neural networks (RNNs) perform element-wise multiplications across the activations of gates. We show that a significant percentage of activations are saturated and propose coarse-grained pruning of activations ...

  • Adding security and privacy to genomic information representation 

    Delgado Mercè, Jaime; Llorente Viejo, Silvia; Naro, Daniel (2019)
    Article
    Open Access
    Provision of security and privacy to genomic data is a key issue in current genomic information representation. Existing formats do not give a solution to these issues (or they provide a partial one), so new solutions are ...

  • A survey on mobility-induced service migration in the fog, edge, and related computing paradigms 

    Rejiba, Zeineb; Masip Bruin, Xavier; Marín Tordera, Eva (2019-09-01)
