低资源自然语言处理的现实实践:开发集

Towards Realistic Practices In Low-Resource Natural Language Processing: The Development Set

摘要:

对于真正的低资源语言,获得开发集是不切实际的,因为使用所有可用的数据进行训练通常更有效。然而,开发集被广泛用于那些声称要处理低资源自然语言处理(NLP)的研究论文中。在这里,我们的目标是回答以下问题:与更现实的替代方案相比,在低资源环境中使用早期停止的开发集是否会影响结果,其中训练时期的数量是根据开发语言调整的?它是否会导致对业绩的高估或低估?我们重复了最近针对低资源NLP的神经模型工作中的多个实验,并比较了通过使用和不使用开发集训练获得的模型的结果。平均而言,不同语言之间的绝对准确度差异高达1.4%。然而,对于某些语言和任务,差异高达18.0%的准确率。我们的研究结果强调了现实的实验设置在低资源NLP研究结果的出版中的重要性。

英文摘要:

Development sets are impractical to obtain for real low-resource languages, since using all available data for training is often more effective. However, development sets are widely used in research papers that purport to deal with low-resource natural language processing (NLP). Here, we aim to answer the following questions: Does using a development set for early stopping in the low-resource setting influence results as compared to a more realistic alternative, where the number of training epochs is tuned on development languages? And does it lead to overestimation or underestimation of performance? We repeat multiple experiments from recent work on neural models for low-resource NLP and compare results for models obtained by training with and without development sets. On average over languages, absolute accuracy differs by up to 1.4%. However, for some languages and tasks, differences are as big as 18.0% accuracy. Our results highlight the importance of realistic experimental setups in the publication of low-resource NLP research results.
