Task: Summarization
The following is copied from the authors' README.
We train a pegasus model with sampled gap sentence ratios on both C4 and HugeNews, and stochastically sample important sentences. The updated the results are reported in this table.

---|---|---|---|

"Mixed & Stochastic" 模型有以下更改:
(*) wikihow 和 big_patent 数据集的数量不可比较,因为进行了标记化和数据的更改:
"Mixed & Stochastic" 模型与论文中的 pegasus-large 模型相比具有以下更改:
在 C4 和 HugeNews 上进行训练(数据集混合根据示例数量进行加权)。进行了 1.5M 而不是 500k 的训练(我们观察到预训练困惑度较慢)。模型在 15% 和 45% 之间均匀采样空格句子比例。使用 20% 的均匀噪声对重要性分数进行采样。更新了 sentencepiece 分词器以能够编码换行符。
