“…To utilize the interaction effect between genes across multi-omics data, network-based integrative approaches have several advantages, such as utilizing the interrelationships among multi-omics data, better biological interpretation, and improved outcome prediction power, as shown in many studies (Jeong et al, 2015;Kim et al, 2015a;Lee et al, 2019;Vangimalla et al, 2016;Wang et al, 2017;Kim et al, 2017). To effectively combine different types of genomic features on the graph, most network-based integrative methods have focused on incorporating prior knowledge such as pathway or subtype information in many cancer studies (Hung and Chiu, 2017;Liu et al, 2015;Dimitrakopoulos et al, Fig. 1.…”
