Self-organizing feature map (SOFM) is a distinguished data mining tool for academic or practice. It projects the input data on a two or three-dimensional grid called prototypes that help to visualize effectively and explore characteristics of them. While the number of data is large, the researchers can increase the number of node to facilitate quantitative analysis of them. In this paper, we focus on the RFM variables and use different approaches to segment the SOFM prototypes. In particular, general K-means and fuzzy C-means are applied. We execute the technique of SOFM to generate the prototypes in the first place. Then we adopt segment methods in the second phase. The experiment result demonstrates that it performs well when compared with direct segment of the RFM variable. |
