In this tutorial, I’ll show you how to use the Sklearn Logistic Regression function to create logistic regression models in Python. I’ll quickly review what logistic regression is, explain the syntax of Sklearn LogisticRegression, and I’ll show you a step-by-step example of how to use ...
There are multiple ways of dealing with unbalanced data, with one approach being to oversample the minority class (in this case, class=0). I will not go into details here. However, if you are interested in oversampling, you can find a section on it in my previous story on logistic ...
