BoostedTreesAggregateStats

public final class BoostedTreesAggregateStats

Aggregates the summary of accumulated stats for the batch.

The summary stats contains gradients and hessians accumulated for each node, feature dimension id and bucket.

Public Methods

public Output<TFloat32> asOutput ()

Returns the symbolic handle of the tensor.

Inputs to TensorFlow operations are outputs of another TensorFlow operation. This method is used to obtain a symbolic handle that represents the computation of the input.

public static BoostedTreesAggregateStats create (Scope scope, Operand<TInt32> nodeIds, Operand<TFloat32> gradients, Operand<TFloat32> hessians, Operand<TInt32> feature, Long maxSplits, Long numBuckets)

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

Parameters

scope	current scope
nodeIds	int32; Rank 1 Tensor containing node ids for each example, shape [batch_size].
gradients	float32; Rank 2 Tensor (shape=[batch_size, logits_dimension]) with gradients for each example.
hessians	float32; Rank 2 Tensor (shape=[batch_size, hessian_dimension]) with hessians for each example.
feature	int32; Rank 2 feature Tensors (shape=[batch_size, feature_dimension]).
maxSplits	int; the maximum number of splits possible in the whole tree.
numBuckets	int; equals to the maximum possible value of bucketized feature.

Returns

• a new instance of BoostedTreesAggregateStats

public Output<TFloat32> statsSummary ()

output Rank 4 Tensor (shape=[splits, feature_dimension, buckets, logits_dimension + hessian_dimension]) containing accumulated stats for each node, feature dimension and bucket.
