model = TFBertForSequenceClassification.from_pretrained("bert-base-uncased") tokenizer = BertTokenizer.from_pretrained("bert-base-uncased") 1. 2. 有很多方法可以对文本序列进行向量化,例如使用词袋 (BoW)、TF-IDF、Keras 的 Tokenizers 等。在这个实现中,我们将使用预训练的“bert-base-uncase”标记器类....
BERT has revolutionized the NLP field by enabling transfer learning with large language models that can capture complex textual patterns, reaching the state-of-the-art for an expressive number of NLP applications. For text classification tasks, BERT has already been extensively explored. However, ...

Demonstrating that further adaptation on sub-domain data can improve the pre-training of BERT model for specific tasks; Utilizing the edge probing technique to explore the ignored knowledge in the last layer of BERT model; The SLL fine-tuning mechanism is proposed to utilize all the available kno...
learning rate adjustment, model strategy adjustment. In the course of the experiment, we found that the effect of BERT+CRF is very small compared with the simple BERT+Softmax. The reason is that the pre-training model can learn features with obvious discrimination after fine-tuning, which leads...
Sentiment analysis neural network trained by fine-tuning BERT, ALBERT, or DistilBERT on the Stanford Sentiment Treebank. - barissayil/SentimentAnalysis
we group NLP tasks into clusters based on their task types and hold out each cluster for evaluation while instruction tuning FLAN on all other clusters. 首先在包括commonsense reasoning、machine translation、sentiment analysis等NLP task上进行微调,然后在从未见过的natural language inference任务上进行...
