== 关键技术与方法 == === 传统方法 === 早期自然语言处理依赖人工编写的语法规则与词典,后发展为基于统计的 n-gram 语言模型、隐马尔可夫模型(HMM)与条件随机场(CRF)等概率方法。 === 词向量与表示学习 === Word2Vec、GloVe 等词嵌入技术将词语映射为稠密向量,使语义相近的词在向量空间中彼此接近,为神经网络处理语言奠定了基础。 === 循环神经网络 === 循环神经网络(RNN)及其变体长短期记忆网络(LSTM)擅长处理序列数据,曾长期是机器翻译与文本生成的主流架构。 === Transformer 与预训练模型 === 2017 年提出的 Transformer 架构凭借自注意力机制高效建模长距离依赖,催生了 BERT、GPT 等预训练语言模型。"预训练 + 微调"范式成为现代自然语言处理的标准方法,并最终演化出参数规模庞大的 [[大语言模型]]。
