WebJun 15, 2024 · Now finding the best binary partition in terms of minimum sum of squares is generally computationally infeasible. Hence we proceed with a greedy algorithm. Starting with all of the data, consider a splitting variable j and split point s , and define the pair of half-planes R 1 ( j, s) = { X X j ≤ s } and R 2 ( j, s) = { X X j > s }
