tf.data.experimental.scan

A transformation that scans a function across an input dataset.

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.

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.

A Dataset transformation function, which can be passed to tf.data.Dataset.apply.
