Embodiment Construction
[0059] The present invention will be further described below in conjunction with specific examples.
[0060] This embodiment uses the cervical cancer project (CESC) data in the public cancer data set TCGA to evaluate the method of the present invention, and uses different types of patients as evaluation indicators. The outline design of this example is as follows figure 1 As shown, the implementation process is as follows figure 2 As shown, the specific process of realizing the multi-omics cancer data integration analysis method based on similarity fusion based on similarity fusion is as follows:
[0061] Step 1. Obtain the gene expression data, methylation data, and miRNA data of the same batch of samples of the cervical cancer project in the TCGA database. In this example, the data of 292 cervical cancer patients were initially collected.
[0062] Step 2, data cleaning: process the null values in the data, delete more than 20% of the samples or features directly, and use...
