Testing Kaggle forum ideas
Unfortunately, not all the Forum posts and Kernels are necessarily useful for your model. So instead of blindly incorporating ideas into your pipeline, you should test them first.
You're given a function get_cv_score(), which takes a train dataset as an argument and returns the overall validation root mean squared error over 3-fold cross-validation. The train DataFrame is already available in your workspace.
You should try different suggestions from the Kaggle Forum and check whether they improve your validation score.
