WebJun 22, 2011 · For a three-way split, you can split into A, B, and C by first splitting into A&B versus C and then splitting out A from B. A given algorithm might not choose that particular sequence (especially if, like most algorithms, it's greedy), but it certainly could. WebAug 8, 2024 · A decision tree, while performing recursive binary splitting, selects an independent variable (say X j) and a threshold (say t) such that the predictor space is split into regions { X X j < t } and { X X j >= t }, and which leads to greatest reduction in cost function. Now let us suppose that we have a variable with categorical values in { X }.
