Rule Extraction for Screening of COVID-19 Disease Using Granular Computing Approach
Algorithm 2
Algorithm to construct granular tree.
Result: A granular tree | (1) Compute Conditional Entropy, Confidence, Generality and Coverage for attribute-values in information table | (2) Select attribute-values with entropy =0 | (3) Specify priority of attribute-values with zero entropy according to highest generality and highest coverage | (4) Choose instance of attribute-values with zero entropy, as set B | (5) Define as | (6) If then | If then Extract rules and stop | Else Define and goto (1) | Else Add attribute-value that its instance highest coverage with | (7) Add instance of this attribute-value to B and goto (5) |
