Spectral clustering is well known to relate to partitioning of a mass-spring system, where each mass is associated with a data point and each spring stiffness corresponds to a weight of an edge describing a similarity of the two related data points, as in the spring system. Specifically, the … Ver mais In multivariate statistics, spectral clustering techniques make use of the spectrum (eigenvalues) of the similarity matrix of the data to perform dimensionality reduction before clustering in fewer dimensions. The similarity matrix is … Ver mais Denoting the number of the data points ny $${\displaystyle n}$$, it is important to estimate the memory footprint and compute time, or number of arithmetic operations (AO) performed, as a function of $${\displaystyle n}$$. No matter the algorithm of the … Ver mais The ideas behind spectral clustering may not be immediately obvious. It may be useful to highlight relationships with other methods.
