The equations look fine to me - I was a math major in college. Honestly, I get so tired of humanities people -- or programmers, bragging about how much they hate math. Except: https://gist.github.com/benmcredmond/0dec520b6ab2ce7c59d5#file-kmeans-rb https://gist.github.com/benmcredmond/0dec520b6ab2ce7c59d5#fi... I didn't know k-means clustering was that simple. I am taking notes... * pick two centers at random run 15 times: * for each post, find the closest center * take the average point of your two clusters as your new center This is cool. It is 2-means clustering and we can extend it to 5 or 13... We don't need any more math, as long as we don't ask whether this algorithm converges or how quickly
