how to calculate the distance between two centers in K-means algorithm?
显示 更早的评论
I need to get access to centers which are generated in each iteration of K-means algorithm to calculate the distance between to the new center and the older one,actually I want to calculate centers displacements, I mean〖dis〗_k=‖〖c_k^'-c〗_k ‖, I wonder how i can do this!

Depends on how distance and displacement are defined, and also how the centres are represented. Typically though, if you have two vectors representing centres, you would subtract one from the other and use the norm function on the result to get the distance.
