How do I use class weights in scikit-learn?
You can use the class_weight parameter in classifiers like LogisticRegression or RandomForestClassifier.
What values can I assign to class_weight?
You can set it to 'balanced', a dictionary mapping class labels to weights, or a float value.
Can you give me an example of using class weights in a model?
Sure! Here's an example: model = RandomForestClassifier(class_weight={0: 1, 1: 5}).
When should I consider using class weights?
Use class weights when you have imbalanced classes to help the model learn better from minority classes.
