摘要:

在这项工作中,我们研究了用户控制的表到文本的生成,用户探索的内容在一个表中选择单元格和阅读的自然语言描述自动产生的自然语言发生器。这样的生成模型通常从仔细选择的单元选中单元组合(干净单元选择)学习;然而,在实践中,用户可能选择意外的、冗余的或不相干的单元组合(有噪声的单元选择)。在实验中,我们发现,模型表现良好的测试集来自相同的分布作为训练数据,但其性能下降时,现实的嘈杂的用户输入进行评估。我们提出了一个微调制度,额外的用户模拟嘈杂的细胞选择。使用所提出的机制进行微调的模型在用户嘈杂的测试用例中获得4.85个BLEU点,在干净的测试用例中获得1.4个BLEU点;并在ToTTo数据集上实现了相当的最先进性能。

英文摘要:

In this work we study user controlled table-to-text generation where users explore the content in a table by selecting cells and reading a natural language description thereof automatically produce by a natural language generator. Such generation models usually learn from carefully selected cell combinations (clean cell selections); however, in practice users may select unexpected, redundant, or incoherent cell combinations (noisy cell selections). In experiments, we find that models perform well on test sets coming from the same distribution as the train data but their performance drops when evaluated on realistic noisy user inputs. We propose a fine-tuning regime with additional user-simulated noisy cell selections. Models fine-tuned with the proposed regime gain 4.85 BLEU points on user noisy test cases and 1.4 on clean test cases; and achieve comparable state-of-the-art performance on the ToTTo dataset.
