title: Outlier detection in data mining
body: <p>I have a few sets of questions regarding outlier detection:</p>
  
  <ol>
  <li><p>Can we find outliers using k-means and is this a good approach?</p></li>
  <li><p>Is there any clustering algorithm which does not accept any input from the user?</p></li>
  <li><p>Can we use support vector machine or any other supervised learning algorithm for outlier detection?</p></li>
  <li><p>What are the pros and cons of each approach?</p></li>
  </ol>
