TreeEnsembleRegressor (ai.onnx.ml)#
Tree Ensemble regressor. Returns the regressed values for each input in N.
All args with nodes_ are fields of a tuple of tree nodes, and it is assumed they are the same length, and an index i will decode the tuple across these inputs. Each node id can appear only once for each tree id.
All fields prefixed with target_ are tuples of votes at the leaves.
A leaf may have multiple votes, where each vote is weighted by the associated target_weights index.
All fields ending with <i>_as_tensor</i> can be used instead of the same parameter without the suffix if the element type is double and not float. All trees must have their node ids start at 0 and increment by 1.
Mode enum is BRANCH_LEQ, BRANCH_LT, BRANCH_GTE, BRANCH_GT, BRANCH_EQ, BRANCH_NEQ, LEAF
Attributes
aggregate_function: Defines how to aggregate leaf values within a target. One of ‘AVERAGE,’ ‘SUM,’ ‘MIN,’ ‘MAX.’ Default value is
nameaggregatefunctionsSUMtypeSTRING
(STRING)base_values: Base values for classification, added to final class score; the size must be the same as the classes or can be left unassigned (assumed 0) default value cannot be automatically retrieved (FLOATS)
base_values_as_tensor: Base values for classification, added to final class score; the size must be the same as the classes or can be left unassigned (assumed 0) default value cannot be automatically retrieved (TENSOR)
n_targets: The total number of targets. default value cannot be automatically retrieved (INT)
nodes_falsenodeids: Child node if expression is false default value cannot be automatically retrieved (INTS)
nodes_featureids: Feature id for each node. default value cannot be automatically retrieved (INTS)
nodes_hitrates: Popularity of each node, used for performance and may be omitted. default value cannot be automatically retrieved (FLOATS)
nodes_hitrates_as_tensor: Popularity of each node, used for performance and may be omitted. default value cannot be automatically retrieved (TENSOR)
nodes_missing_value_tracks_true: For each node, define what to do in the presence of a NaN: use the ‘true’ (if the attribute value is 1) or ‘false’ (if the attribute value is 0) branch based on the value in this array. This attribute may be left undefined and the defalt value is false (0) for all nodes. default value cannot be automatically retrieved (INTS)
nodes_modes: The node kind, that is, the comparison to make at the node. There is no comparison to make at a leaf node. One of ‘BRANCH_LEQ’, ‘BRANCH_LT’, ‘BRANCH_GTE’, ‘BRANCH_GT’, ‘BRANCH_EQ’, ‘BRANCH_NEQ’, ‘LEAF’ default value cannot be automatically retrieved (STRINGS)
nodes_nodeids: Node id for each node. Node ids must restart at zero for each tree and increase sequentially. default value cannot be automatically retrieved (INTS)
nodes_treeids: Tree id for each node. default value cannot be automatically retrieved (INTS)
nodes_truenodeids: Child node if expression is true default value cannot be automatically retrieved (INTS)
nodes_values: Thresholds to do the splitting on for each node. default value cannot be automatically retrieved (FLOATS)
nodes_values_as_tensor: Thresholds to do the splitting on for each node. default value cannot be automatically retrieved (TENSOR)
post_transform: Indicates the transform to apply to the score. One of ‘NONE,’ ‘SOFTMAX,’ ‘LOGISTIC,’ ‘SOFTMAX_ZERO,’ or ‘PROBIT’ Default value is
nameposttransformsNONEtypeSTRING
(STRING)target_ids: The index of the target that each weight is for default value cannot be automatically retrieved (INTS)
target_nodeids: The node id of each weight default value cannot be automatically retrieved (INTS)
target_treeids: The id of the tree that each node is in. default value cannot be automatically retrieved (INTS)
target_weights: The weight for each target default value cannot be automatically retrieved (FLOATS)
target_weights_as_tensor: The weight for each target default value cannot be automatically retrieved (TENSOR)
Inputs
X (heterogeneous)T: Input of shape [N,F]
Outputs
Y (heterogeneous)tensor(float): N classes
Type Constraints
T tensor(float), tensor(double), tensor(int64), tensor(int32): The input type must be a tensor of a numeric type.
