WebThe greedy algo detects the split here at iteration 8 (ie between 8th and 9th row). Assuming this is the last step ang best model F3 with lowest MSE. The process is the same as before. WebSplitting is a process of dividing a node into two or more sub-nodes. When a sub-node splits into further sub-nodes, it is called a Decision Node. Nodes that do not split is called a Terminal Node or a Leaf. When you remove sub-nodes of a decision node, this process is called Pruning. The opposite of pruning is Splitting. how does a dog\u0027s brain work
