Abstract

A new concept of Reduct computation is proposed. This set is referred as NewReduct. It is discovered by defining the Indiscernibility matrix modulo (iDMM D) and Indiscernibility function modulo(iDFM D). Reduct is known as interesting and important set of attributes that able to represent the IS, in adverse the NewReduct is set of superfluous, redundant and non-interesting attributes. The computation of attributes defines sets of dispensable attributes and the partitioning of the objects based on indiscernibility relations shaped the information of a new knowledge. It is assumed that the sets of NewReduct attributes are able to uncover hidden knowledge that lies under a hidden pattern. One important knowledge that may be discovered from the IS or DS is the outliers knowledge.
