Francisco J. Universitat Politècnica de Catalunya Av. Article received on November 15, ; accepted on January 01, This method is used as a prior step in a regression problem, considered as differnece learning problem in which the output variable can be either quantitative continuous or discreet or qualitative defined over an ordinal scale.

In the case of continuous outputs, the method is based on the maximization of the difference between distributions by using intervalar distances. In the case of qualitative outputs, what is a persistent variable qualitative andd is defined over a structure of absolute orders of magnitude. The main characteristics of the dfiference presented are illustrated (avriable) three examples, two for continuous outputs and the last for a qualitative output.

En este trabajo se presenta una nueva técnica para definir las fronteras en el proceso de discretización de una variable continua. Este método es usado como paso previo en un problema de regresión, considerado como un problema de aprendizaje en el cual la variable de salida puede ser cuantitativa continua o discreta o cualitativa definida sobre una escala ordinal. El método propuesto enfatiza el concepto de "localidad" para determinar las fronteras de las discretización.

En el caso fata variables continuas, el método se basa en la maximización de la diferencia entre distribuciones usando distancias intercalares, y en el caso de salidas cualitativas, en una distancia definida sobre una estructura de órdenes de magnitud absolutos.
