You could also supply it with just one seed. Then you can think of that
seed as a point that is the center of a circle. The radius of the circle is
the bandwidth.
In a nutshell, the algorithm will just shift that circle around until it
covers as many points as possible. It decides on the direction of each
shift by finding the centroid of the points covered by the circle.
But as the others say, one nice feature of mean shift is that it discovers
the number of clusters.

All the data continuously generated in your IT infrastructure contains a
definitive record of customers, application performance, security
threats, fraudulent activity and more. Splunk takes this data and makes
sense of it. Business sense. IT sense. Common sense.
