Hi,
In kmeans we need to specify number of clusters and directory of initial
vectors. When you want random initial vectors, specify k (-k 5) and directory
for initial vectors -or in this case where they will be saved. This is
specified by -c ./cluster-directory/initial (thats my preference). You can
obviously specify any location.
