tf.compat.v1.data.experimental.scan
tf.data.experimental.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 areinitial_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. |
| Returns |
|---|
| A Dataset transformation function, which can be passed totf.data.Dataset.apply. |
