classifyDecisionTable: CLASSIFY DECISION TABLE

In RoughSetKnowledgeReduction: Simplification of Decision Tables using Rough Sets

Description

It applies the Value Reduct object rules to a Decision Table object. It returns an object with new decisions for the rules in the Decision Table object.

Usage

classifyDecisionTable(object, decisionTable)

Arguments

object	A Value Reduct object
decisionTable	A Decision Table object

Value

It returns a Decision Table object which rules have the same conditions of input DT object but the rule decisions of the Value Reduct rules where they match.

exampleMatrix1 <- matrix(c(1,0,2,1,1,2,2,0,0,1,0,1,0,2,1,
1,2,1,0,0,2,0,1,1,2,1,1,2,0,1,1,0,0,2,1,2,1,1,2,1),ncol = 5)

0,0,0,0,2,1,0,0,1,2,2,2,1,1,0,0,2,2,2),ncol = 5)
dt1 <- new(Class="DecisionTable",decisionTable = exampleMatrix1)
dt2 <- new(Class="DecisionTable",decisionTable = exampleMatrix2)
vr1 <- simplifyDecisionTable(dt1)
dt3 <- classifyDecisionTable(vr1,dt2)#It classifies dt2 with the rules obtained from dt1
dt3 <- removeDuplicatedRulesDT(dt3)
