    Hi!

    In some binary classification tasks, there's a concept of "positive" or "negative" outcome. Sometimes you are interested in the precision or the recall of one particular class. For example, in a medical test for cancer, you really want to find cancer. In fraud detection, you really want to find fraud etc.

    You can use the operator Remap Binominals to define the values you'd like to handle as positive and negative. This will help you interpreting the results.
