Both automatic evaluation and human evaluation show that MART generates more satisfying results than previous LSTM-based approaches (Xiong et al., 2018;Zhou et al., 2019;Zhang et al., 2018) and transformer-based approaches (Zhou et al., 2018;.
mART can generate more coherent (e.g., coreference and order), less redundant paragraphs without losing paragraph accuracy (visual relevance).
