Let’s say you have 5000 samples of class dog and 45000 samples of class not-dog than you feed in class_weight = {0: 5, 1: 0.5}. The Situation I want to use logistic regression to do binary classification on a very unbalanced data set. Learn how to lift weights and why you should do it from two qualified personal trainers in a fun and relaxed workout class designed for everybody.
