Cluster Analysis in DNA Microarray Experiments
... Clustering is in some sense a more difficult problem than classification. In general, all the issues that must be addressed for classification must also be addressed for clustering. In addition, with clustering, • there is no learning set of labeled observations; • the number of groups is usually unknow ...

Following the various popular culinary processes in Bayesian nonparametrics, we will start by describing the law of π in terms of the conditional distribution of the cluster membership of each sequence i given those of 1, . . . , i − 1. Since we have a Markov process with a time index, the metaphor ...
