| Abstract: | To find the outlier in a data set more quickly and efficiently,an outlier-analysis based on the gird model was provided.This algorithm gives the way to partition the data space by the grid model,defines the boundary value of judging if there is an outlier existing in one grid,and gives the algorithm,which can be used in detecting the outliers correctly with less time. |
