Why reverse the sequence?

[caiyongqi]

reverse the sequence

us_pois = [list(reversed(upois)) + [0] * (max_len - le) if le < max_len else list(reversed(upois[-max_len:])) for upois, le in zip(inputData, len_data)]

Why reverse the sequence?
Thank you.

Thank you for your interest.
In this work, we incorporate position information into the model by using reversed position vectors, where the first position vector corresponds to the last item. Comparing with reversing position vectors, we found that it is more convenient to reverse the original sequence.
