Table 3 Four Cases of Context Variable14.
From: An Algorithm of Association Rule Mining for Microbial Energy Prospection
Cases (Context) | Proposed Change in Support | |
|---|---|---|
For Positive Rules | Context < CIV | Difference = (CIV − context) * 100/context; New_support_value = actual_support + (actual_support * Difference)/100 |
For Positive Rules | Context > CFV | Difference = (context − CFV) * 100/context; New_support_value = actual_support − (actual support * Difference)/100 |
For Negative Rules | Context < CIV | Difference = (CIV − context) * 100/context; New_support_value = actual_support − (actual support * Difference)/100 |
For Negative Rules | Context > CFV | Difference = (context − CFV) * 100/context; New_support_value = actual_support + (actual support * Difference)/100 |
