    On K-means algorithm with the use of Mahalanobis distances
    (Statistics & Probability Letters, 2014-01-01) Melnykov, Igor; Melnykov, Volodymyr; Igor, Melnykov
    Abstract The K-means algorithm is commonly used with the Euclidean metric. While the use of Mahalanobis distances seems to be a straightforward extension of the algorithm, the initial estimation of covariance matrices can be complicated. We propose a novel approach for initializing covariance matrices.
