Hi, Dr. Zhou,
Thanks for your great work.
What do bos_mask and bos_token mean and what do they do. The abbreviations make it strange.

HiVT/datasets/argoverse_v1_dataset.py

Line 121 in 6876656

bos_mask = torch.zeros(num_nodes, 20, dtype=torch.bool)

HiVT/models/local_encoder.py

Line 136 in 6876656

self.bos_token = nn.Parameter(torch.Tensor(historical_steps, embed_dim))
