That is, given a very large;multi-dimensional dataset, and a limited amount of resources;(e.g., running time and memory), design and implement algorithms;to efficiently and accurately (1) identify the sparse and crowded regions;(clustering analysis), (2) estimate the density function of the overall;data distribution (density analysis). They are very important and practical;branches of data mining, and can be applied to many domains such as, data;classification, image compression and pattern recognition.; Recent Research Project; BIRCH: An Efficient Data Clustering and Density Analysis System for Very Large Databases.; Selected Publications; Data Clustering System BIRCH and Its Applications (Tian Zhang, Raghu Ramakrishnan, Miron Livny),;submitted to Data Mining and Knowledge Discovery Journal, June, 1996, U.S.A.; BIRCH: An Efficient Data Clustering Method for Very Large Databases (Tian Zhang, Raghu Ramakrishnan, Miron Livny),;in Proc. of ACM SIGMOD Int'l Conf. on Data Management,;June 1996, Canada.; Interactive Classification of Very Large Datasets with BIRCH (Tian Zhang, Raghu Ramakrishnan, Miron Livny),;in Proc. of Workshop on Research Issues on Data Mining and Knowledge;Discovery (in cooperation with ACM-SIGMOD'96), June 1996, Canada.; Fast Density and Probability Estimations Using CF-Kernel Method for Very Large Databases;(Miron Livny, Raghu Ramakrishnan, Tian Zhang),;Technical Report, July, 1996.;Motion Planning of Multi-joint Robotic Arm with Topological Dimension;Reduction Method;(Bo Zhang, Ling Zhang, Tian Zhang),;in Proc. of 11th.
