    • Border algorithms for computing Hasse diagrams of arbitrary lattices 

      Balcázar Navarro, José Luis; Tirnauca, Cristina (Springer, 2011)
      Conference report
      Restricted access - publisher's policy
      Lattices are mathematical structures with many applications in computer science; among these, we are interested in fields like data mining, machine learning, or knowledge discovery in databases. One well-established use ...

    • Closed-set-based discovery of representative association rules revisited 

      Balcázar Navarro, José Luis; Tirnauca, Cristina (Hermann Éditions, 2011)
      Conference report
      Open Access
      The output of an association rule miner is often huge in practice. This is why several concise lossless representations have been proposed, such as the “essential” or “representative” rules. We revisit the algorithm given ...

    • Mining educational data for patterns with negations and high confidence boost 

      Balcázar Navarro, José Luis; Tirnauca, Cristina; Zorrilla Pantaleón, Marta Elena (2010)
      Conference report
      Restricted access - publisher's policy
      Association rules constitute a well-known and widely employed data mining technique. We study their applicability in Educational Data Mining. We develop a case study of datasets from that eld: logs of an e-learning ...
