1. Introduction 现有的大多数研究使用的视觉transformers都是遵循着Vit中使用的传统表现方案,也就是将一幅完整的图像切分成多个patch构成成一个序列信息。这样操作可以有些的捕获各个patch之间的序列视觉序列信息(visual sequential information)。然而现在的自然图像的多样性非常高,将给定的图像表示为一个个局部的patch可以...

BERT(Bidirectional Encoder Representations from Transformers),是Google2018年提出的预训练模型,即双向Transformer的Encoder,因为decoder是不能获要预测的信息的。模型的主要创新点都在pre-train方法上,即用了Masked LM(MLM)和Next Sentence Prediction(NSP)两种方法分别捕捉词语和句子级别的representation。

为了使用 BERT 解决这个任务,首先将单个句子改成以下格式:[CLS] Sentence [SEP],然后将其输入BERT 模型,获取 [CLS] 的输出特征,并将其连接到一个 Softmax 分类器,以计算损失并进行反向传播。具体如图 3 所示(这是原始 BERT 论文,应该是忘记在最后一个句子后面追加 [SEP] token 了)。
from transformers import BertTokenizer, BertTokenizerFromPretrained # 加载预训练模型 model = BertTokenizerFromPretrained.from_pretrained('bert-base-uncased') # 使用模型进行文本标记化 text = "This is an example sentence." tokens = model.tokenize(text) ``` 在上述示例中,我们首先导入了BertTokenizer和...
But now, in the decoder part, we want the algorithm to create one token each time only considering the previous ones already generated. To make this work properly, we need to forbid the tokens from getting information from the right of the sentence. This is done by masking the matrix of ...
