    • closedAccess   A penalized likelihood method for nonseparable space–time generalized additive models 

      Mosammam, Ali M.; Mateu, Jorge Springer Verlag (2018-07)
      In this paper, we study space-time generalized additive models. We apply the penalyzed likelihood method to fit generalized additive models (GAMs) for nonseparable spatio-temporal correlated data in order to improve the ...

    • openAccess   Environment-Aware Regression for Indoor Localization based on WiFi Fingerprinting 

      Mendoza-Silva, Germán Martín; Costa, Ana Cristina; Torres-Sospedra, Joaquín; Painho, Marco; Huerta, Joaquin Institute of Electrical and Electronics Engineers (2021-04-19)
      Data enrichment through interpolation or regression is a common approach to deal with sample collection for Indoor Localization with WiFi fingerprinting. This paper provides guidelines on where to collect WiFi samples, and ...

    • openAccess   Influence of Measured Radio Map Interpolation on Indoor Positioning Algorithms 

      Bravenec, Tomáš; Gould, Michael; Fryza, Tomas; Torres-Sospedra, Joaquín IEEE (2023-07-24)
      Indoor positioning and navigation increasingly have become popular, and there are many different approaches, using different technologies. In nearly all of the approaches, the locational accuracy depends on signal propagation ...

    • openAccess   Situation Goodness Method for Weighted Centroid-Based Wi-Fi APs Localization 

      Mendoza-Silva, Germán Martín; Torres-Sospedra, Joaquín; Huerta, Joaquin; Montoliu Colás, Raul; Benítez, Fernando; Belmonte-Fernández, Óscar Springer (2016-10-13)
      Knowing the location of Wi-Fi antennas may be critical for indoor localization. However, in a real environment, their positions may be unknown since they can be managed by external entities. This paper introduces a new ...
