If I have two dataset (A,B) with binary class, class distribution (pos:neg ratio) for A is 50:125 and for B, it is 50:225. Are both of them imbalanced?

What is the rule to say the data set is class-imbalanced?

Dr. Indrajit Mandal

But if it is like 1:10, then it is imbalanced.

As you get more experienced, it depends on you to decide that...

I hope it helps you.

Best regards
