On the decomposition of tabular knowledge systems.
Recently there has been a growing interest in the decomposition of knowledge based systems and decision tables. Much work in this area has adopted an informal approach. In this paper, we first formalize the notion of decomposition, and then we study some interesting classes of decompositions. The proposed classification can be used to formulate design goals to master the decomposition of large decision tables into smaller components. Importantly, carrying out a decomposition eliminates redundant information from the knowledge base, thereby taking away -right from the beginning- a possible source of inconsistency. This, in turn, renders subsequent verification and validation more smoothly.Knowledge; Systems;
An overview of decision table literature.
The present report contains an overview of the literature on decision tables since its origin. The goal is to analyze the dissemination of decision tables in different areas of knowledge, countries and languages, especially showing these that present the most interest on decision table use. In the first part a description of the scope of the overview is given. Next, the classification results by topic are explained. An abstract and some keywords are included for each reference, normally provided by the authors. In some cases own comments are added. The purpose of these comments is to show where, how and why decision tables are used. Other examined topics are the theoretical or practical feature of each document, as well as its origin country and language. Finally, the main body of the paper consists of the ordered list of publications with abstract, classification and comments.
An谩lisis de la Interpretabilidad de la Salud 脫sea con 脕rboles de Decisi贸n Difusa
Hoy en d铆a, la salud 贸sea es un campo de la medicina el cual ha tomado mucho inter茅s,
porque cada vez son m谩s comunes las enfermedades relacionadas a los huesos.
El objetivo principal de este proyecto es el an谩lisis de la interpretabilidad de la salud 贸sea,
con la ayuda de un programa de escritorio, el cual tiene por modelo un 谩rbol de decisi贸n
difusa y este nos proporciona las reglas. Se han recolectado datos antropom茅tricos y usado
f贸rmulas de regresi贸n para calcular la densidad 贸sea de escolares entre 12 y 18 a帽os de los
colegios Inmaculada Concepci贸n y Jorge Basadre del sector de Arequipa Per煤, clasificados
seg煤n edad y sexo. Se tomo los datos de escolares, porque, los huesos se desarrollan en
edades tempranas, y diferenciamos entre g茅neros, porque existe una notoria diferencia entre
hombre y mujer al producir densidad 贸sea. Al analizar en la herramienta Weka los 5
algoritmos, se ha determinado que el mejor algoritmo entre estos es el 谩rbol de injerto (graft
tree) con un porcentaje de clasificaci贸n del 92.42% seg煤n le conjunto de datos obtenidos.
Para el an谩lisis de la interpretabilidad se tom贸 en cuenta el n煤mero de reglas, las variables
ling眉铆sticas y la simplicidad de las reglas.
