Most Popular Data Mining Algorithms

Just saw this post on the Data Mining Research blog about a summary paper on the top 10 data mining algorithms as voted by the program committees of KDD, ICDM and SDM. The paper gives a really nice introduction to and summary of a bunch of particularly useful algorithms. It is a great starting point for somebody interested in finding out more about data mining. Some of the sections are better written than others - I particularly liked the discussions regarding support vector machines (SVM) and k-nearest neighbor (kNN) classification.
