tf.raw_ops.BoostedTreesAggregateStats

robots: noindex

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.

node_ids A Tensor of type int32. int32; Rank 1 Tensor containing node ids for each example, shape [batch_size].
gradients A Tensor of type float32. float32; Rank 2 Tensor (shape=[batch_size, logits_dimension]) with gradients for each example.
hessians A Tensor of type float32. float32; Rank 2 Tensor (shape=[batch_size, hessian_dimension]) with hessians for each example.
feature A Tensor of type int32. int32; Rank 2 feature Tensors (shape=[batch_size, feature_dimension]).
max_splits An int that is >= 1. int; the maximum number of splits possible in the whole tree.
num_buckets An int that is >= 1. int; equals to the maximum possible value of bucketized feature.
name A name for the operation (optional).

A Tensor of type float32.
