Flow clustering without k

WebDec 31, 2014 · K-means isn't "really" distance based. It minimizes the variance. (But variance ∼ squared Euclidean distances; so every point is assigned to the nearest centroid by Euclidean distance, too). There are plenty of grid-based clustering approaches. They don't compute distances because that would often yield quadratic runtime.
