A Tighter Analysis of Spectral Clustering, and Beyond

1 code implementation2 Aug 2022 Peter Macgregor, He Sun

For the second result, we show that, by applying fewer than $k$ eigenvectors to construct the embedding, spectral clustering is able to produce better output for many practical instances; this result is the first of its kind in spectral clustering.
