Distance in Label File   Message List  
Reply | Forward Message #31 of 119 |
Hi,

I have two questions regarding the distance printed in the labels file.

a. Is the distance in the label file correspond to the Euclidean
distance between vestors?

b. Is the distance calculated between the centroid of the cluster and
other vectors in the cluster? I believe in k-means the centroid need
not map to an actual point in the data set. Some clusters did not have
a zero distance value so I guessed the distance would have been
calculated with respect to the centroid chosen by k-means.

Thanks in advance,

Sreekumar
