Reinforced Generative Adversarial Network for Abstractive Text Summarization

no code implementations31 May 2021 Tianyang Xu, Chunyun Zhang

However, these models have three drawbacks: their grasp of the details of the original text is often inaccurate, and the text generated by such models often has repetitions, while it is difficult to handle words that are beyond the word list.
