The rapid development of high-throughput biomedical technologies can provide researchers with detailed multi-omics data. The multi-omics integrated analysis approach based on machine learning contributes a more comprehensive perspective to human disease research. However, there are still significant challenges in representing single-omics data and integrating multi-omics information.
This article presents HyperTMO, a Trusted Multi-Omics integration framework based on Hypergraph convolutional network for patient classification. HyperTMO constructs hypergraph structures to represent the association between samples in single-omics data, then evidence extraction is performed by hypergraph convolutional network, and multi-omics information is integrated at an evidence level. Last, we experimentally demonstrate that HyperTMO outperforms other state-of-the-art methods in breast cancer subtype classification and Alzheimer's disease classification tasks using multi-omics data from TCGA (BRCA) and ROSMAP datasets. Importantly, HyperTMO is the first attempt to integrate hypergraph structure, evidence theory, and multi-omics integration for patient classification. Its accurate and robust properties bring great potential for applications in clinical diagnosis.

高通量生物医学技术的快速发展可以为研究人员提供详细的多组学数据。基于机器学习的多组学综合分析方法为人类疾病研究提供了更全面的视角。然而,在表示单组学数据和整合多组学信息方面仍然存在重大挑战。
本文提出了基于超图卷积网络的 HyperTMO,这是一种用于患者分类的可信多组学集成框架。HyperTMO 构建超图结构来表示单组学数据中样本之间的关联,然后通过超图卷积网络进行证据提取,并在证据水平上整合多组学信息。最后,我们使用 TCGA(BRCA)和 ROSMAP 数据集的多组学数据,在乳腺癌亚型分类和阿尔茨海默病分类任务中实验证明,HyperTMO 优于其他最先进的方法。重要的是,HyperTMO 是首次尝试将超图结构、证据理论和多组学集成用于患者分类。其准确和稳健的特性为临床诊断中的应用带来了巨大的潜力。
