tf_privacy.tree_aggregation.TreeState

Class defining state of the tree.

tf_privacy.tree_aggregation.TreeState(
    level_buffer, level_buffer_idx, value_generator_state
)

Attributes
level_buffer: A `tf.Tensor` saves the last node value of the left child entered for the tree levels recorded in `level_buffer_idx`. level_buffer_idx: A `tf.Tensor` for the tree level index of the `level_buffer`. The tree level index starts from 0, i.e., `level_buffer[0]` when `level_buffer_idx[0]==0` recorded the noise value for the most recent leaf node.
`level_buffer`	A `namedtuple` alias for field number 0
`level_buffer_idx`	A `namedtuple` alias for field number 1
`value_generator_state`	State of a stateful `ValueGenerator` for tree node.
