A transformation that scans a function across an input dataset. (deprecated)
tf.data.experimental.scan(
initial_state, scan_func
)
Warning: THIS FUNCTION IS DEPRECATED. It will be removed in a future version.
Instructions for updating:
Use `tf.data.Dataset.scan(...) instead
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. The new_state
must match the
structure of initial_state
.
