The long-distance agreement, evidence for syntactic structure, is increasingly used to assess the syntactic generalization of Neural Language Models. Much work has shown that transformers are capable of high accuracy in varied agreement tasks, but the mechanisms by which the models accomplish this behavior are still not well understood. To better understand transformers' internal working, this work contrasts how they handle two superficially similar but theoretically distinct agreement phenomena: subject-verb and object-past participle agreement in French. Using probing and counterfactual analysis methods, our experiments show that i) the agreement task suffers from several confounders which partially question the conclusions drawn so far and ii) transformers handle subject-verb and object-past participle agreements in a way that is consistent with their modeling in theoretical linguistics.

本文表明，一种流行的方法，监督嵌入文件的分类，即对比词移动器的嵌入，可以显着提高通过增加可解释性。这种可解释性是通过将聚类促进机制纳入对比损失来实现的。在几个公共数据集上，我们表明我们的方法在现有基线的基础上显着改进，同时通过识别一组最能代表特定类别的关键字来提供对集群的解释。我们的方法的动机部分是需要开发自然语言处理（NLP）方法的\textit{novel problem of assessing student work for scientific writing and thinking} -一个问题，是中央（教育）学习科学（LS）的领域。在这种情况下，我们表明，我们的方法导致一个有意义的评估学生的工作相关的实验室报告，从生物类，可以帮助LS研究人员深入了解学生的理解和评估科学思维过程的证据。
