WebMay 28, 2015 · Normally, adjacency matrices are defined as symmetric. However, according to ( 2 ), the matrices are defined as upper triangular, thus the redundant information storage is avoided allowing greater efficiency in the use of sparse matrices. WebI'm a little at loss as to what my supervisor meant by the "hierarchical block decomposition" of a matrix, but the goal is to put a sparse symmetric adjacency matrix into a block diagonal structure to highlight the structure of the clusters present in the data.(The data captures whether the two proteins are adjacent in a molecule: if they are, the corresponding …
