I have a unbalanced dataset with 5 classes. Now i want so undersample it to make it more balanced. But i can´t find a code for this, just for binary class problems.

Do someone have a sample code?

  • If you want to be helped more efficiently, you should be more specific by showing a extract of your data, the needed results and the code you have so far or at least a reference to the code you're talking about. – manu190466 May 19 '20 at 21:42
