Association rule mining is an important component of data mining. In the last years a great number of algorithms have been proposed with the objective of solving the obstacles presented in the generation of association rules. In this work, we offer a revision of the main drawbacks and proposals of solutions documented in the literature, including our own ones. The work is focused also in the cl...

In this paper, we construct the first known infinite family of primitive Qpolynomial schemes which are not generated by distance-regular graphs. To construct these examples, we introduce the notion of a relative hemisystem of a generalized quadrangle with respect to a subquadrangle.

Two scientific European organizations in the field of consultationliaison (C-L) psychiatry and psychosomatic medicine (PM), the European Association of Consultation-Liaison Psychiatry and Psychosomatics (EACLPP) and the European Network of Psychosomatic Medicine (ENPM) decided to merge and together create a new society, the European Association of Psychosomatic Medicine (EAPM). The EACLPPwas fo...

Several Methods are proposed for associate rule generation. They try to solve two problems related to redundancy and relevance of associate rules. In this paper we introduce a method called CONDCLOSE which provides the reduction of PRINCE algorithm run-time proposed by Hamrouni and al. in 2005.In fact, we show how the notions of pseudo context and condensed context which we introduce in this pa...
