摘要:

医疗专业人员经常在数据受限的环境中工作,以提供对独特人口统计的见解。例如,一些医学观察为病人的诊断和治疗提供了信息。这为元学习提供了一种独特的设置,一种在新任务上快速学习模型的方法,以提供其他方法无法获得的见解。我们研究了在基准文本和医疗数据的广泛语料库上使用元学习和鲁棒性技术。为此,我们开发了新的数据管道,将语言模型与元学习方法相结合,并扩展了现有的Meta学习算法,以最大限度地减少最坏情况下的损失。我们发现,元学习的文本是一个合适的框架,基于文本的数据,提供更好的数据效率和可比性能的Few-Shot语言模型,可以成功地应用于医疗笔记数据。此外,元学习模型结合DRO可以改善疾病代码的最坏情况损失。

英文摘要:

Medical professionals frequently work in a data constrained setting to provide insights across a unique demographic. A few medical observations, for instance, informs the diagnosis and treatment of a patient. This suggests a unique setting for meta-learning, a method to learn models quickly on new tasks, to provide insights unattainable by other methods. We investigate the use of meta-learning and robustness techniques on a broad corpus of benchmark text and medical data. To do this, we developed new data pipelines, combined language models with meta-learning approaches, and extended existing meta-learning algorithms to minimize worst case loss. We find that meta-learning on text is a suitable framework for text-based data, providing better data efficiency and comparable performance to few-shot language models and can be successfully applied to medical note data. Furthermore, meta-learning models coupled with DRO can improve worst case loss across disease codes.
