Hi, thanks for the great work! I'm wondering why should we randomly discard a unit_length motion with a one-third probability in getitem function of Text2MotionDatasetEval class and Text2MotionDataset class? Why discard it and why with a one-third probability? https://github.com/EricGuo5513/momask-codes/blob/7ac5c2784dee403461558a722f0fdfdf36a3a849/data/t2m_dataset.py#L211-L212 Thank you in advance for your reply.

Hi, thanks for your interest.

We just follow the benchmark setting from HumanML3D. Probably, it's for some augmentation.
