The rules of LRFs and CE are shown in 2-D. (a) LRFs of the synthetic data set. The LRFs usually have relatively small magnitude in the central regions of the clusters and with relatively large magnitude at the border regions. (b) Points with CE > 0 are represented with red dotted-markers, most of which are located in center areas.
