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. WebMar 24, 2024 · Freecyto’s application of k-means clustering quantization vastly reduces the complexity of the flow cytometry data, without significant loss to the variability within the original dataset as we ...
