Automatic Summarization of Small Samples Based on Enhanced Regularization
摘要
Abstract
Automatic text summarization aims to extract the main statements from text information for the pur-pose of compressing information.Existing generative automatic summarization methods do not take full advantage of the pre-trained model to learn the semantics of the original text,resulting in the loss of important information in the generated content,when the data set with a small number of samples is often prone to overfitting.In order to solve such problems and obtain better fine-tuning performance,the pre-trained model mT5(multilingual T5)is used as a baseline to improve the learning ability of the model by combining R-drop(Regularized dropout)with reinforced regularity for model fine-tuning,and Sparse softmax is used to reduce the ambiguity of prediction generation to en-sure the accuracy of the output.The model calculates BLEU(Bilingual Evaluation Understudy)for hyperparameter test on Chinese data sets LCSTS and CSL,and uses Rouge as evaluation index to evaluate data sets of different orders of magnitude.The experimental results show that the optimized pre-trained model can better learn the semantic rep-resentation of the original text,and the model can maintain a good fit in the small samples and generate more practi-cal results.关键词
