    • openAccess   Mapping microarray gene expression data into dissimilarity spaces for tumor classification 

      García, Vicente; Sánchez Garreta, Josep Salvador Elsevier (2015-02)
      Microarray gene expression data sets usually contain a large number of genes, but a small number of samples. In this article, we present a two-stage classification model by combining feature selection with the ...

    • closedAccess   Mapping the intensity function of a non-stationary point process in unobserved areas 

      Gabriel, Edith; Rodríguez-Cortés, Francisco Javier; Coville, jerome; Mateu, Jorge; Chadoeuf, Joël Springer (2022)
      Seismic networks provide data that are used as basis both for public safety decisions and for scientific research. Their configuration affects the data completeness, which in turn, critically affects several seismological ...
