NMath Stats Tutorial

Clustering Analysis, Part II: K-Means Clustering

In this continuing series, we explore the NMath Stats functions for performing cluster analysis in .NET. (For previous posts, see here.) The sample data set we're using classifies 89 single malt scotch whiskies on a five-point scale (0-4) for 12 flavor characteristics. To visualize the data set and clusterings, we make use of the free Microsoft Chart Controls for .NET, which provide a basic set of...

Clustering Analysis, Part I: Principal Component Analysis (PCA)

Cluster analysis or clustering is the assignment of a set of observations into subsets (called clusters) so that observations in the same cluster are similar in some sense. Cluster analysis is the assignment of a set of objects into one or more clusters based on object similarity. NMath Stats includes a variety of techniques for performing cluster analysis, which we will explore in a series of p...
