positiveLabel property
A value using to encode positive class.
Example:
Given a positive class label equals 100
Given a negative class label equals -100
Given a dataset
feature_1 | feature_2 | feature_3 | target class 1 | target class 2 | target class 3
123 | 233 | 444 | 100 | -100 | -100
333 | 100 | 101 | 100 | -100 | -100
321 | 911 | 321 | -100 | 100 | -100
221 | 987 | 222 | -100 | -100 | 100
908 | 404 | 503 | -100 | 100 | -100
If a prediction algorithm meets 100 in a target column, it will interpret the value as a positive outcome for the corresponding class
Implementation
num get positiveLabel;
