13 .Project introduction Model Core method defects CBOW (to predict the central word by the nearby word) Can't solve the problem of polysemy, no word2vec skip-gram (to predict the nearby word by the central word) contextual information Dynamic adjustment of Word Embedding based on the ELMO uses LSTM as feature extractor, and ELMo current context LSTM is much weaker than Transformer in feature extraction GPT's pre-training uses a one-way language model, using Using a one-way language model (no bi- openAI GPT only the words above to predict the words directional [forward, reverse] extraction), can not understand the text well Bert adopts the exact same two-stage model as GPT: Because the network is more complex, the BERT First, language model pre-training; computation is larger, and the training Second, the fine-tuning mode was used to solve the convergence is slower downstream tasks © 2020 Zilliz.

14 .Project introduction The BERT model uses Transformer as the main framework for the algorithm, which captures the bi- directional relationships in statements more thoroughly. Google provides a number of pre-trained models, the two most basic of which are the Bert-base model and the Bert-Large model. © 2020 Zilliz. All rights reserved.
