En diversos problemas de reconocimiento de patrones, se ha observado que el desequilibrio de clases puede disminuir el desempeño del clasificador, principalmente en los patrones de las clases minoritarias. Una estrategia para resolver el problema del desbalance, consiste en tratar por separado las clases incluidas en el problema (clase minoritaria o mayoritaria), a fin de equilibrar los conjuntos de datos. En este sentido, la motivación del presente artículo estriba en el hecho de que el modelo asociativo visto como Clasificador Híbrido Asociativo con Traslación (CHAT), es muy sensible al des-balance de las clases. Por ello, se analiza el impacto que los conjuntos de datos des-balanceados pueden tener sobre el rendimiento del CHAT. Adiciona...
