title: how to choose initial centroids for k-means clustering
body: <p>I am working on implementing k-means clustering in Python. What is the good way to choose initial centroids for a data set? For instance: I have following data set:</p>
  
  <pre><code>A,1,1
  B,2,1
  C,4,4
  D,4,5
  </code></pre>
  
  <p>I need to create two different clusters. How do i start with the centroids?</p>
