BoostedTreesTrainingPredict

public final class BoostedTreesTrainingPredict

Runs multiple additive regression ensemble predictors on input instances and

computes the update to cached logits. It is designed to be used during training. It traverses the trees starting from cached tree id and cached node id and calculates the updates to be pushed to the cache.

Public Methods

static BoostedTreesTrainingPredict
create(Scope scope, Operand<?> treeEnsembleHandle, Operand<Integer> cachedTreeIds, Operand<Integer> cachedNodeIds, Iterable<Operand<Integer>> bucketizedFeatures, Long logitsDimension)
Factory method to create a class wrapping a new BoostedTreesTrainingPredict operation.
Output<Integer>
nodeIds()
Rank 1 Tensor containing new node ids in the new tree_ids.
Output<Float>
partialLogits()
Rank 2 Tensor containing logits update (with respect to cached values stored) for each example.
Output<Integer>
treeIds()
Rank 1 Tensor containing new tree ids for each example.
