    The Forest Tool in Alteryx implements a random forest.Random forests are pretty neat. They leverage ensemble learning to use what are typically considered to be weak learners (Decision Trees) to create a stronger and more robust modeling method.. Random forest models are composed of decision trees, so it is important to make sure you understand the trees before taking on the forest
