WebAccording to the class assignment rule, we would choose a class that dominates this leaf node, 3 in this case. Therefore, this leaf node is assigned to class 3, shown by the number below the rectangle. In the leaf node to its right, class 1 with 20 data points is most dominant and hence assigned to this leaf node. WebLeaf nodes are the nodes of the tree that have no additional nodes coming off them. They don't split the data any further; they simply give a classification for examples that end up in that node.
