In this video I continue the tutorial series on machine learning in R to talk about the following topics: modifying boundaries for classifier thresholds, creating ROC curves, and ensembling the results of multiple models. We will supplement the "caret" package with "ROCR" and "caretEnsemble".
There are a few sources from which this tutorial draws influence and structure. The first is the GitHub documentation on "caret" from its creation, Max Kuhn. The second is a very well-written and comprehensive tutorial by author Selva Prabhakaran on Machine Learning Plus. Third is a helpful resource for dealing with class imbalance, as we often find with classification problems.
