    We demonstrate how graph decomposition techniques can be employed for the visualization of hierarchical co-occurrence patterns between medical data items. Our research is based on Gaifman graphs (a mathematical concept ...
  • Feature selection for microarray gene expression data using simulated annealing guided by the multivariate joint entropy 

    González Navarro, Félix Fernando; Belanche Muñoz, Luis Antonio (2014-04-01)
    Article
    Open Access
    Microarray classification poses many challenges for data analysis, given that a gene expression data set may consist of dozens of observations with thousands or even tens of thousands of genes. In this context, feature ...
  • Closed-set-based discovery of representative association rules
