type tree =

| Split of {
1. split_indice : int;
2. split_condition : float;
3. left : tree;
4. right : tree;
5. missing : [ `Left ];
}
| Leaf of {
1. leaf_value : float;
}

type op =

| Identity
| Sigmoid

type t = {

base_score : float;
trees : tree array;
after_sum : op;

}

the value is op(base_score + sum(tree))
