A novel repetition normalized adversarial reward for headline generation
Peng Xu ; Pascale Fung ;
Date 19 Feb 2019
AbstractWhile reinforcement learning can effectively improve language generation models, it often suffers from generating incoherent and repetitive phrases cite{paulus2017deep}. In this paper, we propose a novel repetition normalized adversarial reward to mitigate these problems. Our repetition penalized reward can greatly reduce the repetition rate and adversarial training mitigates generating incoherent phrases. Our model significantly outperforms the baseline model on ROUGE-1,(+3.24), ROUGE-L,(+2.25), and a decreased repetition-rate (-4.98\%).
