摘要:

机器学习(ML)被广泛用于从电子健康记录(EHR)中自动提取有意义的信息,以支持运营,临床和财务决策。然而,ML模型需要大量带注释的示例来提供令人满意的结果,这在大多数医疗保健场景中是不可能的,因为临床医生标记的数据成本很高。主动学习(AL)是选择信息量最大的实例由专家标记以进一步训练监督算法的过程。我们证明了AL在临床领域的多标签文本分类的有效性。在这种情况下,我们应用一组众所周知的AL方法来帮助自动分配MIMIC-III数据集上的ICD-9代码。我们的研究结果表明,信息实例的选择提供了令人满意的分类与显着减少的训练集(8.3%的总实例)。我们得出结论,AL方法可以显着降低手动注释成本,同时保持模型的性能。

英文摘要:

Machine Learning (ML) is widely used to automatically extract meaningful information from Electronic Health Records (EHR) to support operational, clinical, and financial decision-making. However, ML models require a large number of annotated examples to provide satisfactory results, which is not possible in most healthcare scenarios due to the high cost of clinician-labeled data. Active Learning (AL) is a process of selecting the most informative instances to be labeled by an expert to further train a supervised algorithm. We demonstrate the effectiveness of AL in multi-label text classification in the clinical domain. In this context, we apply a set of well-known AL methods to help automatically assign ICD-9 codes on the MIMIC-III dataset. Our results show that the selection of informative instances provides satisfactory classification with a significantly reduced training set (8.3\% of the total instances). We conclude that AL methods can significantly reduce the manual annotation cost while preserving model performance.
