instance weighting J48

[hubert39]

Hi guys,

I have trouble with instance weighting.
Because of the unbalanced datasets, I have to use the instance weighting. However, I cannot find the way to implement it.
Does anyone have the source or article for me to study and implement?

Regards,
Hubert

Hi,
I got my way.
CostSensitiveClassifier+j48
Now, I'm trying to combine this two classifiers.^^
