WebbLearning Decision Trees - Machine Learning. In the context of supervised learning, a decision tree is a tree for predicting the output for a given input. We start from the root of the tree and ask a particular question about the input. Depending on the answer, we go down to one or another of its children. The child we visit is the root of ... Webb4 jan. 2024 · Decision Trees are perhaps one of the simplest and the most intuitive classification methods in a Machine Learning toolbox. The first occurrence of Decision Trees appeared in a publication by William Belson in 1959. Earlier uses of Decision Trees were limited to Taxonomy for their natural semblance for that type of data.
