COMPARISON OF CLUSTERING ALGORITHMS FOR SPEAKER IDENTIFICATION Nikolay Lubimov, Evgeny Mikheev, Alexey Lukin Moscow Lomonosov State University, Moscow, Russia In this paper we consider the problem of text-independent speaker identification that refers to acoustic recognition research. ... We have performed the comparison of different clustering methods for speaker identification: the standard K-means clustering, K-means++, Linde-Buzo-Gray, Fuzzy C-means, and Gustafson-Kessel algorithms. ...

. filename : Cross-device link . The file you are trying to make a link to is located on a different physical device. The solution is to create a symbolic link . directory_name is a directory . You are trying to make a link to a directory. Check the pathname for the file. ln: filename : File exists . A file with the same name as the linkname already exists in the destination directory. Use a different name for the linkname.
