  3. More precise initialization of centroids.

    authored
    The previous method was to assign input vectors to centroids
    from head. It is of course important that each initial centroid
    is correspond to either of input vector, so that the result
    will be balanced. So, the new method is to split the vector space
    made by all the inputs into k pieaces and assign nearest input
    to the centroid.
