Appendix A Notations Symbol Description S

In this part, we list the main notations in Table S1 for clear reference. Table S1: Main notations used in the work. The detailed procedure of the proposed method is summarized in Algorithm 1. Algorithm 1 Pseudocode of the Proposed Method. We compared our proposed model with the following weakly-supervised methods for cancer prognosis analysis. WSISA [1]: The candidate patterns are clustered by the K-Means algorithm based on the phenotype features of tiles, followed by several DeepConvSurv [2] models to find important clusters.
