;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

;; K-means is a Clustering Algorithm.

;; We use it when we have some data, and we want to split the data into separate categories.

;; For instance, an early biologist, let's call him Adam, might measure all
;; sorts of things about the living objects he encounters in the world.

remap prefix to Control + a
