Webb16 mars 2024 · A nice aspect of using tree-based machine learning, like Random Forest models, is that that they are more easily interpreted than e.g. neural networks as they are based on decision trees. So, when I am using such models, I like to plot final decision trees (if they aren’t too large) to get a sense of which decisions are underlying my predictions.

WebbAs you can see, the decision tree model results are the same regardless of the library, since I split the data and set up cross-validation the same way. Moreover, both tidymodels and caret use rpart as the underlying engine. So it seems strange that tidymodels takes over 1 minute while caret only needs 4–5 seconds to run decision tree.
