WebMulti-head Attention is a module for attention mechanisms which runs through an attention mechanism several times in parallel. The independent attention outputs are then concatenated and linearly transformed into the expected dimension. Web15 apr. 2024 · Transformer 模型是 Google 在 2024 年提出的一种神经网络结构,用于解决自然语言处理中的序列建模任务。相比于传统的循环神经网络(如 LSTM 和 GRU),Transformer 模型具有更好的并行计算性能和更短的训练时间。Transformer 模型采用自注意力机制(Self-Attention)来处理序列数据。
