%X Phenomena of "curse of dimensionality" deteriorate lots of existing outlier mining algorithms validity. Conconing thw problem, the outlier mining algorithm of high-dimension and large datasets based on information theory was proposed. This algorithm used the concept of information entropy and the mutual information in the information theory,carried on the feature selection after using estimated mutual information value objective basis entropy power sorting, and eliminated redundant attribute for dimensionality reduction. Outlier mining using information entropy as a measure standard to judge eliminated the drawbacks of distance and density metric. The experimental result in the real data sets indicates that the algorithm for outlicr mining in high-dimensional mass data is effective and feasible, its efficiency and accuracy arc significantly improved.
