Research and Development of Self-organizing Maps Algorithm

The self-organizing maps(SOM) is an unsupervised learning algorithm,which is capable of self organization and visualization and has been used in many areas.In this paper,the background of self-organizing maps algorithm and basic algorithm are introduced,the parameter setting-up and disadvantage of SOM are analyzed.The improved algorithms have been reviewed emphatically,and research hotspot and applying fields are also discussed briefly.Finally,some remarks on future research are given.
