Table 47 Summary for recognizing minority and majority instances on highly imbalanced datasets
From: Resampling imbalanced data for network intrusion detection datasets
|  | Influence on minority’s recall | Influence on minority’s precision | Influence on majority’s recall | Influence on majority’s precision | Overall Influence on recall and precision |
|---|---|---|---|---|---|
Recognize more minority instances correctly | Increase | Increase | No influence | No influence | Increase recall Increase precision |
Recognize more majority instances incorrectly | No influence | Decrease | Little influence | Little influence | Decrease precision |
Combined influence | Increase | Decrease | Little influence | Little influence | Increase recall Decrease precision |
