这在概念上类似于信息检索中使用的查询扩展技术,该技术可以重新制定给定的查询以提高检索性能。 【5】Language Models as Knowledge Bases? 这是Facebook AI research的一篇论文,将LM作为“知识”的基石,基于Bert提出了在公开的预训练模型下的 事实与常识知识系统Bert-large,并鼓励大家使用bert-large作为研究的起点。
该方法的具体实现为,将预训练的Transformer模型参数整体Freeze住,当正常输入文本序列的时候,在最前端添加几个prefix id,每一个prefix id都对应一个随机初始化的embedding,不同的任务有不同的prefix id。这样在模型中,prefix之后每个时刻的表示都会受到prefix的影响,prefix代表某个对应具体任务的上下文信息。在Finetune过程...

Prefix-Tuning也是很经典的参数有效性学习,其是受到Prompt-Tuning的启发。我们说Prompt-Tuning的本质是参数有效性学习,是因为整个预训练模型参数可以全部固定,只需要对Template对应的少量参数(例如连续模板的Prompt Encoder、伪标记对应的Embedding等)进行训练。在Prefix-Tuning中,则是除了对输入层添加模板外,还对Transformer...

左图表示的是基于连续提示的Prompt-Tuning(例如P-tuning),我们可以发现只有输入层对应模板部分的Embedding和MLP参数是可训练的,右图部分表示Prefix-Tuning(P-tuning V2),Transformer的每一层的前缀部分也是可训练的,可以抽象的认为是在每一层添加了连续的模板。但是实际上,Prefix-Tuning(P-tuning V2)并不是真正的在每...
