In this chapter, we consider the same classification problem as in Chap. 5: for a given decision table T and a new object v it is required to generate a value of the decision attribute on v using values of conditional attributes on v. To this end, we divide the decision table T into a number of information systems Si, i ∈ Dec (T), where Dec (T) is the set of values of the decision attribute in T. For i ∈ Dec (T), the information system Si contains only objects (rows) of T with the value of the decision attribute equal to i. © 2009 Springer-Verlag Berlin Heidelberg.
