BERT模型在THUNCNews数据集上的分类性能评估

In order to evaluate the classification performance of the model, this study fine-tuned the BERT pre-trained model on the THUNCNews dataset. After several rounds of training, an excellent BERT classification model on the THUNCNews dataset was obtained. Specifically, this study calculated the classification precision, recall, and F1 value of the model on each news category, and the results were summarized in Table 2.
