title: Performance Analysis of Clustering Algorithms
body: <p>I have been given 2 data sets and want to perform cluster analysis for the sets using KNIME.</p>
  
  <p>Once I have completed the clustering, I wish to carry out a performance comparison of 2 different clustering algorithms. </p>
  
  <p>With regard to performance analysis of clustering algorithms, would this be a measure of time (algorithm time complexity and the time taken to perform the clustering of the data etc) or the validity of the output of the clusters? (or both)</p>
  
  <p>Is there any other angle one look at to identify the performance (or lack of) for a clustering algorithm?</p>
  
  <p>Many thanks in advance,</p>
