La Sociedad de la Información y el Conocimiento con su constante evolución tecnológica ha traído aparejados grandes y acelerados cambios sociales en los más variados aspectos de nuestra vida diaria. Y que ocurre con el Derecho? Por supuesto aprovecha las…

This article proposes a method for achieving an appropriate balance between the parameters of support, precision, and simplicity during the evolution of classification rules by means of genetic programming. The method includes an adaptive procedure in order to achieve such…

Defeasible argumentation is one of the approaches that attempt to address the challenges arising when we reason defeasibly, with several formalisms in the literature reaching a mature state. Nowadays, several of them started shifting their semantics towards a dialectical characterization.…

The knowledge of guava fruiting cycle is of great interest not only due to its biological aspects but also as an important datum for the application of cultural practices. This paper was carried out in the Submedio São Francisco region…

Although BNs have been used successfully for many medical diagnosis problems, there have been few applications to epidemiological data where data mining methods play a significant role. In this paper, we look at the application of BNs to epidemiological data,…

A la fi de l’edat mitjana, el naixement de la burgesia provoca una revisió profunda en diversos àmbits. A grans trets, aquest nou col·lectiu reclama l’accés al saber, fins aleshores reservat a la noblesa. En particular, hi ha un interés…
