A transformation that scans a function across an input dataset. (deprecated)
tf.contrib.data.scan(
initial_state, scan_func
)
This transformation is a stateful relative of tf.data.Dataset.map.
In addition to mapping scan_func across the elements of the input dataset,
scan() accumulates one or more state tensors, whose initial values are
initial_state.
Args |
|---|
initial_state
|
A nested structure of tensors, representing the initial state
of the accumulator.
|
scan_func
|
A function that maps (old_state, input_element) to
(new_state, output_element). It must take two arguments and return a
pair of nested structures of tensors. Thenew_statemust match the
structure ofinitial_state`.
