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. WebbDALEX is designed to work with various black-box models like tree ensembles, linear models, neural networks etc. Unfortunately R packages that create such models are very inconsistent.

Webb15 juli 2024 · By Julia Silge in rstats tidymodels. July 15, 2024. Lately I’ve been publishing screencasts demonstrating how to use the tidymodels framework, from first steps in modeling to how to evaluate complex models. Today’s screencast focuses on bagging using this week’s #TidyTuesday dataset on astronaut missions. 👩‍🚀. 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.

WebbUnder the hood. The parser is based on the output from the randomForest::getTree () function. It will return as many decision paths as there are non-NA rows in the prediction field. The output from parse_model () is transformed into a dplyr, a.k.a Tidy Eval, formula. The entire decision tree becomes one dplyr::case_when () statement.
