WebNov 19, 2024 · 1 Answer. There are two dimensions d_k and d_v in the original paper. key_dim corresponds to d_k, which is the size of the key and query dimensions for each head. d_k can be more or less than d_v. d_v = embed_dim/num_head. d_v is the size of the value for each head. Strictly speaking, d_v = embed_dim/num_head is not required. Web数据导入和预处理.
