Web11 de abr. de 2024 · BERT adds the [CLS] token at the beginning of the first sentence and is used for classification tasks. This token holds the aggregate representation of the input sentence. The [SEP] token indicates the end of each sentence [59]. Fig. 3 shows the embedding generation process executed by the Word Piece tokenizer. First, the … Web因为Position Encoding是通过三角函数算出来的,值域为[-1, 1]。所以当加上 Position Encoding 时,需要放大 embedding 的数值,否则规模不一致相加后会丢失信息。 因为 Bert 使用的是学习式的Embedding,所以 Bert 这里就不需要放大。 Q: 为什么 Bert 的三个 Embedding 可以进行相加?
Web20 de mar. de 2024 · BERT brought everything together to build a bidirectional transformer-based language model using encoders rather than decoders! To overcome the “see itself” issue, the guys at Google had an ingenious idea. They employed masked language modeling.

Web7 de jan. de 2024 · In this case, the answer lies in BERT’s position embeddings, which are added to the word embeddings at the input layer (see Figure 1). BERT learns a unique position embedding for each of the 512 positions in the input sequence, and this position-specific information can flow through the model to the key and query vectors.
