答案是可以,具体是需要通过BertForMaskedLM并结合Prompt来实现。 二、数据的构建 上面提到Bert模型主要是训练Masked语言模型,要想通过和训练Masked语言模型一样的方式来进行文本分类,首先需要转换任务的形式,具体而言就是把label的预测通过Mask的预测来完成。同时可以结合Prompt进行数据的构建,以新闻预测为例,可以把数据构建...
通过对 bertformaskedlm 的源码进行解读,可以更好地理解其原理和实现方式。 2. BERT 模型简介 BERT(Bidirectional Encoder Representations from Transformers)是由 Google 在 2018 年提出的一种预训练语言模型。与传统的单向语言模型不同,BERT 能够双向地学习文本的语境和语义信息,从而在各种自然语言处理任务中取得了...

Some weights of the model checkpoint at bert-large-uncased were not used when initializing BertForMaskedLM: ['cls.seq_relationship.weight', 'cls.seq_relationship.bias'] - This IS expected if you are initializing BertForMaskedLM from the checkpoint of a model trained on another task or with ...
Im working on a Multiclass Classification (Bengali Language Sentiment Analysis) on a pretrained Huggingface (BertForMaskedLM) model. When the error occured I knew I have to change the label(output) size to match the input. But do not know how. Im adding the code snippents be...
