Worse AUC but better metrics (Recall, Precision) on a classification problem - How can this ...
Here's how it may happen: AUC-ROC calculation is based in Sensitivity and Specificity values, both of which are based on the correctly predicted values, both Positive and Negative:
Sensitivity = True … the other hand are based on the True Positive values:
Precision = Positive Predictive Value = TPos / (TPos + FPos)
Recall (same as Sensitivity) = True Positive Rate = TPos / (TPos + FNeg)
Note that AUC-ROC …
