Feature scalingis a vital step in the preprocessing pipeline.1Decision treesand random forests are two of the very fewmachine learning algorithmswhere one does not need to worry about feature scaling. However,
Description ElenaNKn I don't think there is any bug here. There are a couple of things that can trigger differences in the prediction: Tie breaking can lead to different trees even setting the random state; Even scaling the data, you could potentially get a different tree due to the tree...
