Transcribed Image Text:Key:
Red centroid
Blue centrold
In the figure above, you're given seven points {x1,..., 17}, and you'd like to cluster them into
two groups (red and blue) using the K-means algorithm. You begin by guessing the location of the
red and blue centroids, as shown in the figure above.
Step 1: ,
Assign points to clusters
Based on these initial guesses for the centroids, which of the seven points should be
placed in the red group/cluster, and which in the blue?
Step 2:
Update centroids
Based on your solution above, determine the new location of cach of the red and
blue centroids. Either mark that on the same figure, or describe where you'd like to
place the two centroids.
Step 3: |
, Iterate
Imagine you were to iterate through steps 1 and 2 multiple times. Docs r2 then end
up in the red cluster or in the blue cluster? Justify your response.
