Python K means clustering
<p>I am trying to implement the code on this website to estimate what value of K I should use for my K means clustering.</p>

<p><a href="https://datasciencelab.wordpress.com/2014/01/21/selection-of-k-in-k-means-clustering-reloaded/" rel="nofollow">https://datasciencelab.wordpress.com/2014/01/21/selection-of-k-in-k-means-clustering-reloaded/</a></p>

<p>However I am not getting any success - in particular I am trying to get the f(k) vs the number of clusters k graph which I can use to procure the ideal value of k to use.</p>

<p>My data format is as follows:</p>

<p>Each of the coordinates have 5 dimensions/variables i.e. they are data points that live in a five-dimensional space.
The list of the coordinates are below, where for example the first data point has coordinates <code>( 35.38361202590826,-24.022420305129415, 0.9608968122051765, -11.700331772145386, -9.4393980963685)</code>.</p>

<p>I am able to use scikit-learn to create clusters with these coordinates however I am interested in finding the optimal k value to use - however scikit-learn does not have a feature where I can estimate the optimal value of K with this technique (or any technique as far as I am aware).</p>
