QUAC: Quick unsupervised anisotropic clustering
Completely unsupervised clustering algorithm for multidimensional data. Anisotropicit does not assume spherical clusters or use isotropic kernels. Fastan excellent tool for performing rapid cluster analysis on datamuch faster than mean-shift. Excellent initialisation for a Gaussian mixture model. Qualitative and quantitative results show superiority over well-known methods in accuracy and speed.
