Factory method to create a class wrapping a new BoostedTreesUpdateEnsemble operation.
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
