WebApr 9, 2024 · Decision trees use multiple algorithms to decide to split a node into two or more sub-nodes. The creation of sub-nodes increases the homogeneity of the resulting sub-nodes. The decision tree splits the nodes on all available variables and then selects the split which results in the most homogeneous sub-nodes and therefore reduces the impurity.

WebFeb 20, 2024 · The Decision Tree works by trying to split the data using condition statements (e.g. A < 1 ), but how does it choose which condition statement is best?
