Border algorithms for computing Hasse diagrams of arbitrary lattices Balcázar Navarro, José Luis; Tirnauca, Cristina (Springer, 2011)
Restricted access - publisher's policyLattices 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)
Open AccessThe 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)
Restricted access - publisher's policyAssociation 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 ...
