Rough Sets Data Analysis in Knowledge Discovery: A Case of Kuwaiti Diabetic Children Patients

Algorithm 3

Rule generation and classification.

Input: reduct sets 𝑅_final={𝑟₁∪𝑟₂∪…∪𝑟_𝑛}

Output: Set of rules

1: for each reduct 𝑟 do

2:  for each correspondence object 𝑥 do

3:   Contract the decision rule (𝑐₁=𝑣₁∧𝑐₂=𝑣₂∧…∧𝑐_𝑛=𝑣_𝑛)→𝑑=𝑢

4:   Scan the reduct 𝑟 over an object 𝑥

5:   Construct (𝑐_𝑖,1≤𝑖≤𝑛)

6:   for every 𝑐∈𝐶 do

7:    Assign the value 𝑣 to the correspondence attribute 𝑎

8:   end for

9:   Construct a decision attribute 𝑑

10:   Assign the value 𝑢 to the correspondence decision attribute 𝑑

11:  end for

12: end for
