We show that kk-means (Lloyd's algorithm) is obtained as a special case when truncated variational EM approximations are applied to Gaussian Mixture Models (GMM) with isotropic Gaussians. In contrast to the standard way to relate kk-means and GMMs, the provided derivation shows that it is not required to consider Gau…
