AbstractIn previous work we have demonstrated a heuristic approach to
spectral clustering which automatically determines the number of
clusters that appear in the data set. Here we present a possible
probabilistic interpretation for this, where the correct
clustering can be found by minimising the Kullback-Leibler (KL)
divergence between the affinity matrix and an appropriate Gaussian approximation. [Edit]
