How to Increase class recall of a yes column in confusion matrix

HI All,

I have a split validation operator within which i have a MetaCost operator connected to apply model and performance (binomial) operator. Within the MetaCost, i have a logistic regression operator. The confusion matrix shows my yes and no columns but i would like to increase my recall percentage. How do i do that?

    You can try the Threshold operators (Create and Apply Threshold, see the operators for tutorials regarding their use) and then set your Performance Metric to use Recall as its primary metric of concern.
    P.S.  You should use Cross Validation instead of Split Validation :-)
