Cobweb clustering
http://www.litech.org/~wkiri/Papers/wagstaff-constraints-00.pdf WebThe problem description in this proposed methodology, referred to as attribute-related cluster sequence analysis, is to identify a good working algorithm for clustering of protein structures by comparing four existing algorithms: k-means, expectation maximization, farthest first and COB.
Cobweb clustering

WebThe incremental clustering procedure, based on the merging and splitting operations, was introduced in systems called Cobweb for nominal attributes ( Fisher, 1987) and Classit for numeric attributes ( Gennari et al., 1990 ). Both are based on a measure of category utility that had been defined previously ( Gluck and Corter, 1985 ).

Web3. COB Conceptual Clustering Conceptual clustering is a machine-learning paradigm for clustering. It is different than other clustering algorithms in that it generates a concept descriptor for each cluster. COB [DHFisher87] is one of the mostly commonly used algorithms for conceptual clustering. In this paper, we extend the WebCOB is an incremental system for hierarchical conceptual clustering. COB incrementally organizes observations into a classification tree. Each node in a classification tree represents a class (concept) and is labeled by a probabilistic concept that summarizes the attribute-value distributions of objects classified under the node.
