title: Good data set for Pre-processing
body: <p>I am enrolled in an under-graduate course in Data Mining and I've got an assignment to code a Data Mining Pre-processor. I have the liberty to choose the programming language and the data set. I was wondering if anybody could suggest a good data set to use. I have been going through the <a href="http://archive.ics.uci.edu/ml/index.html" rel="nofollow">UCI Repository</a> and I've found many more such resources. But being a beginner I am not sure which data set would be a good choice. The preprocessor should be dealing with the following stuff:</p>
  
  <ul>
  <li>Data cleaning
  <ul>
  <li>Missing Values</li>
  <li>Errors</li>
  <li>Outliers</li>
  <li>Nomralization</li>
  <li>De-duplication</li>
  </ul></li>
  <li>Data Reduction
  <ul>
  <li>Sampling Techniques</li>
  <li>Dimensionality Reduction</li>
  </ul></li>
  </ul>
  
  <p>What kind of properties should I consider when choosing the data set? Any specific data set you would suggest?</p>
