Hi, i have a question regarding the class weights in SVC. I have an imbalanced binary classification problem. In my case the ratio between the positive class and the negative class is 4:1. I just want to know if setting class weight to:
class_weight = {1: 0.25, 0: 1} is the same to setting it to:
class_weight = {1: 1, 0: 4}.
Because in my case i obtain differents results using the two definition of the class weight
