极简删除引发的罕见但严重的神经机器翻译错误:基于中英文的实证研究

Rare but Severe Neural Machine Translation Errors Induced by Minimal Deletion: An Empirical Study on Chinese and English

Haverford College(哈弗福德学院)

Ruikang Shi, Alvin Grissom, Duc Minh Trinh

AI总结:

该实证研究发现在中英神经机器翻译中,仅删除源文本单个字符即可诱发严重错误,并比较了删字与删词的影响及训练数据规模的作用。

摘要:

我们研究了在基于字符的模型下,通过极简删除源文本来诱发英中、中英领域内神经机器翻译产生罕见但严重错误的现象。仅删除单个字符即可诱发严重的翻译错误。我们对这些错误进行了分类,并比较了删除单个字符与单个单词的结果。我们还考察了训练数据规模对由这些极小扰动诱发的病态案例的数量和类型的影响,发现了显著的差异。研究发现,删除一个单词比删除一个字符对整体翻译得分的损害更大,但在删除字符时某些错误更容易发生,且语言方向也会影响该效果。

英文摘要:

We examine the inducement of rare but severe errors in English-Chinese and Chinese-English in-domain neural machine translation by minimal deletion of the source text with character-based models. By deleting a single character, we can induce severe translation errors. We categorize these errors and compare the results of deleting single characters and single words. We also examine the effect of training data size on the number and types of pathological cases induced by these minimal perturbations, finding significant variation. We find that deleting a word hurts overall translation score more than deleting a character, but certain errors are more likely to occur when deleting characters, with language direction also influencing the effect.
