I am very interested in designing new efficient data mining algorithms ortools for very large databases by integrating the techniques of <B>databases</B>, <B>artificial intelligence</B> and <B>statistics</B>. </UL><UL>My Ph.D thesis topic is on <B>clustering</B> and <B>density</B>analysis of very large datasets. 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, dataclassification, image compression and pattern recognition. </UL><H2> Recent Research Project </H2><UL><!WA8><!WA8><!WA8><!WA8><!WA8><!WA8><!WA8><!WA8><!WA8><!WA8><!WA8><!WA8><!WA8><!WA8><!WA8><!WA8><A HREF="http://www.cs.wisc.edu/~zhang/birch.html"> BIRCH</A>: An Efficient Data Clustering and Density Analysis System for Very Large Databases.</UL> <H2> Selected Publications </H2><UL><LI><!WA9><!WA9><!WA9><!WA9><!WA9><!WA9><!WA9><!WA9><!WA9><!WA9><!WA9><!WA9><!WA9><!WA9><!WA9><!WA9><A HREF="http://www.cs.wisc.edu/~zhang/kbspaper.ps"> Data Clustering System BIRCH and Its Applications</A> (Tian Zhang, Raghu Ramakrishnan, Miron Livny),submitted to Data Mining and Knowledge Discovery Journal, June, 1996, U.S.A.</UL><UL><LI><!WA10><!WA10><!WA10><!WA10><!WA10><!WA10><!WA10><!WA10><!WA10><!WA10><!WA10><!WA10><!WA10><!WA10><!WA10><!WA10><A HREF="http://www.cs.wisc.edu/~zhang/sigmodpaper.ps"> BIRCH: An Efficient Data Clustering Method for Very Large Databases</A> (Tian Zhang, Raghu Ramakrishnan, Miron Livny),in Proc. of ACM SIGMOD Int'l Conf. on Data Management,June 1996, Canada.</UL><UL><LI><!WA11><!WA11><!WA11><!WA11><!WA11><!WA11><!WA11><!WA11><!WA11><!WA11><!WA11><!WA11><!WA11><!WA11><!WA11><!WA11><A HREF="http://www.cs.wisc.edu/~zhang/sigmodworkshop.ps"> Interactive Classification of Very Large Datasets with BIRCH</A> (Tian Zhang, Raghu Ramakrishnan, Miron Livny),in Proc. of Workshop on Research Issues on Data Mining and KnowledgeDiscovery (in cooperation with ACM-SIGMOD'96), June 1996, Canada.</UL><UL><LI><!WA12><!WA12><!WA12><!WA12><!WA12><!WA12><!WA12><!WA12><!WA12><!WA12><!WA12><!WA12><!WA12><!WA12><!WA12><!WA12><A HREF="http://www.cs.wisc.edu/~zhang/paper.ps"> Fast Density and Probability Estimations Using CF-Kernel Method for Very Large Databases</A>(Miron Livny, Raghu Ramakrishnan, Tian Zhang),Technical Report, July, 1996.</UL><UL><LI>Motion Planning of Multi-joint Robotic Arm with Topological DimensionReduction Method(Bo Zhang, Ling Zhang, Tian Zhang),in Proc. of 11th.
