tf.data.experimental.group_by_reducer( key_func, reducer )
This transformation maps element of a dataset to a key using
key_func and groups the elements by key. The
reducer is used to process each group; its
init_func is used to initialize state for each group when it is created, the
reduce_func is used to update the state every time an element is mapped to the matching group, and the
finalize_func is used to map the final state to an output value.
