Parameters

scope	current scope
treeEnsembleHandle	Handle to the ensemble variable.
featureIds	Rank 1 tensor with ids for each feature. This is the real id of the feature that will be used in the split.
nodeIds	List of rank 1 tensors representing the nodes for which this feature has a split.
gains	List of rank 1 tensors representing the gains for each of the feature's split.
thresholds	List of rank 1 tensors representing the thesholds for each of the feature's split.
leftNodeContribs	List of rank 2 tensors with left leaf contribs for each of the feature's splits. Will be added to the previous node values to constitute the values of the left nodes.
rightNodeContribs	List of rank 2 tensors with right leaf contribs for each of the feature's splits. Will be added to the previous node values to constitute the values of the right nodes.
maxDepth	Max depth of the tree to build.
learningRate	shrinkage const for each new tree.
pruningMode	0-No pruning, 1-Pre-pruning, 2-Post-pruning.

Returns

• a new instance of BoostedTreesUpdateEnsemble
