Abstract: IMVOM,Outlier Mining Model Based on ICA ＆ MViSOM, is presented in this paper. This model firstly transforms an observed multidimensional random vector into mutually independent components by ICA, and then achieves visibility of high-dimensional data by MV

Key words: Outlier, ICA（ independent component analysis）, MViSOM （Modified Visualization-Induced Self-Organizing Maps）
