Thepaper discusses distributed data mining algorithms, methods and trends to discover knowledge from distributed data in an effective and efficient way. Introduction data mining is a process of nontrivial extraction of implicit, previously unknown, and potentially useful information such as knowledg e rules, constraints, and regularities from data in databases. Improving distributed data mining techniques by means of a grid infrastructure. Learn a fi nal model directly from the probing set. The aim of privacy preserving distributed data mining is to extract relevant knowledge from large amount of data while protecting at the same time sensitive.
Data mining technology normally adopts data integration method to generate data warehouse. Distributed storage is essential for quality data mining. In the latter method, computation is distributed among heterogeneous sites at local level and data is hosted at global level. This paper investigates mainly on the data mining techniques used in dicom medical imaging which are stored in distributed storage. It also discusses the issues and challenges that must be overcome for designing and implementing successful tools for largescale data mining.
