The classification of objects, into clusters, requires some methods for measuring the Cluster analysis or clustering is the task of grouping a set of objects in such a way that objects in the same group (called a cluster) are more similar (in some sense) to each other than to those in other groups (clusters).

In general, there are many choices of cluster analysis methodology. The hclust function in R uses the complete linkage method for hierarchical clustering by default. This particular clustering method defines the cluster distance between two clusters to be the maximum distance between their …

At MSK he develops predictive models for programs aimed at improving patient care. Prior to this role, Dmitriy completed his Doctorate in Quantitative & Computational Biology at Princeton University. With a passion for teaching and for R, he regularly holds cross-departmental R training sessions within MSK. Cluster analysis involves applying clustering algorithms with the goal of finding hidden patterns or groupings in a dataset. It is therefore used frequently in exploratory data analysis, but is also used for anomaly detection and preprocessing for supervised learning.
