step_rose over_ratio vs minority_prop #144

Open jxu opened 10 months ago

jxu commented 10 months ago

Do they specify the same thing, but with different values? Is "over-sampling the minority class proportion" the same functionality as "ratio of the majority-to-minority frequencies"? And shouldn't it be minority-to-majority ratio if the value is < 1?
