<h2>Schedule</h2>
|
|
<p>In an ideal world, the topics below I estimated being a certain time period for learning them. Of course you have more experience when it comes to how long it actually takes to learn these topics, so I'll leave this mostly to your discretion.</p>
|
|
<p><strong>Distance, Dimensionality Reduction, and Tendency</strong> -- 3 Weeks</p>
|
|
<p><strong>Validating Cluster Models</strong> -- 1 Week</p>
|
|
<p><strong>Connectivity Models</strong> -- 2 Weeks</p>
|
|
<p><strong>Cluster Evaluation</strong> -- 1 Week</p>
|
|
<p><strong>Centroid Models</strong> -- 3 Weeks</p>
|
|
<p><strong>Density Models</strong> -- 3 Weeks</p>
|
|
<p><strong>Analysis of Model Appropriateness</strong> -- 1 Week</p>
|
|
<p>The schedule above accounts for 14 weeks, so there is a week that is free as a buffer.</p>
