English(EN) Three Core Ideas that Make Understanding Attention in Transformers Easy

理解 Transformer:从分词到自注意力机制

本文剖析了 Transformer 模型背后的核心概念,重点介绍了它们如何处理语言。文章解释了分词(tokenization),即将文本分割成更小的片段,以及分词 ID(token IDs),即这些片段的数值表示。该过程继续介绍嵌入(embeddings),将分词转换为捕获它们之间关系的向量,以及位置编码(positional encoding),它为序列中分词的位置添加信息。最后,文章深入探讨了自注意力机制(self-attention),通过使用图书馆搜索的 Query、Key 和 Value 类比,解释了分词如何权衡序列中其他分词的重要性以理解上下文。 AI
