The algorithm is called Clara in R, and is described in chapter 3 of Finding Groups in Data: An Introduction to Cluster Analysis. Kaufman L, Rousseeuw PJ: Finding Groups in Data: An Introduction to Cluster Analysis. Affect inference in learning environments: a functional view of facial affect analysis using naturalistic data. I think Ron Atkin introduced this stuff in the early 1970′s with his q-analysis (see http://en.wikipedia.org/wiki/Q-analysis). An Introduction to Genetic Analysis & CD-Rom [Anthony J.F. The grouping process implements a clustering methodology called "Partitioning Around Mediods" as detailed in chapter 2 of L. The basic idea of TDA is to describe the “shape of the data” by finding clusters, holes, tunnels, etc. Download An Introduction to Genetic Analysis Griffiths Hardcover Book. Hoboken, NJ: John Wiley & Sons, Inc; 1990:1986. Finding Groups in Data: An Introduction to Cluster Analysis Leonard Kaufman, Peter J. In addition to the edges of the graph, we will . Cluster analysis is special case of TDA. United Kingdom The primary objective in both cases was to examine the class separability in order to get an estimate of classification complexity. To extract more topological information— in particular, to get the homology groups— we need to do some more work. There is a specific k-medoids clustering algorithm for large datasets.
