WebDriven by multi-omics data, some multi-view clustering algorithms have been successfully applied to cancer subtypes prediction, aiming to identify subtypes with biometric differences in the same cancer, thereby improving the clinical prognosis of patients and designing personalized treatment plan. WebSpectral Clustering is a technique used to group together data points of similar behavior in order to analyze the overall data. The goal of this project will be to implement a spectral …

WebIn particular, we focus on how meta-path relations are used to construct an effective similarity matrix based on which spectral clustering is done. We formulate the similarity matrix construction as an optimization problem and propose the SClump algorithm for solving the problem. Webutilizes hierarchical clustering on the spectral domain of the graph. Differentfromthek-meansalgorithm,whichdirectlyoutputs results with a predefined number of clusters K and omits the inner connection between the nodes in the same cluster, the hierarchical clustering provides partitioning results with finer intracluster detail.
