Preterm birth is a global epidemic affecting millions of mothers across different ethnicities. The cause of the condition remains unknown but has recognised health-based implications, in addition to financial and economic ones. Machine Learning methods have enabled researchers to combine datasets using uterine contraction signals with various forms of prediction machines to improve awareness of the likelihood of premature births. This work investigates the feasibility of enhancing these prediction methods using physiological signals including uterine contractions, and foetal and maternal heart rate signals, for a population of south American women in active labour. As part of this work, the use of the Linear Series Decomposition Learner (LSDL) was seen to lead to an improvement in the prediction accuracies of all models, which included supervised and unsupervised learning models. The results from the supervised learning models showed high prediction metrics upon the physiological signals being pre-processed by the LSDL for all variations of the physiological signals. The unsupervised learning models showed good metrics for the partitioning of Preterm/Term labour patients from their uterine contraction signals but produced a comparatively lower set of results for the various kinds of heart rate signals investigated.
早产是一种全球性的流行病,影响着数百万不同种族的母亲。这种情况的原因仍然不明,但除了对金融和经济有影响外,还对健康有公认的影响。机器学习方法使研究人员能够将子宫收缩信号数据集与各种形式的预测机器相结合,以提高对早产可能性的认识。这项工作研究了使用包括子宫收缩、胎儿和母亲心率信号在内的生理信号来增强这些预测方法对一群正在分娩的南美妇女的可行性。作为这项工作的一部分,线性序列分解学习器(LSDL)的使用被认为能提高所有模型的预测准确率,这些模型包括监督学习模型和无监督学习模型。监督学习模型的结果表明,在对所有生理信号变化进行LSDL预处理后的生理信号上,预测指标很高。无监督学习模型在根据子宫收缩信号对早产/足月分娩患者进行划分方面显示出良好的指标,但对于所研究的各种心率信号,其结果相对较低。
