From: BRANEnet: embedding multilayer networks for omics data integration
Overview of BRANEnet. Inputs (X) and (Y) are on the left. A multilayer network \({ \bar{\mathbf {A}}}\) is composed of intra- and inter-omics relationships. For \({\bar{\mathbf {A}}}\), the random walk-based PPMI matrix \({\mathbf {S}}\) is computed. To obtain embeddings, \({\mathbf {S}}\) is factorized and the final embeddings \(\varvec{\Omega }_d\) are obtained
