WebHow to construct the affinity matrix. ‘nearest_neighbors’: construct the affinity matrix by computing a graph of nearest neighbors. ‘rbf’: construct the affinity matrix using a radial basis function (RBF) kernel. ‘precomputed’: interpret X as a precomputed affinity matrix, where larger values indicate greater similarity between ... WebJul 1, 2024 · The similarity scores between all the object-related functional networks were quantified using the SimiN et algorithm, which produce a 78 × 78 similarity matrix. The similarity matrix was transformed into a graph where nodes represent brain networks and edges represent the highest similarity score between the brain networks.
